Kitty health issue, need advice.
13 years ago
normally wouldn't post something like this here, but I have a large audience here so I figure my chance of getting some answers is a lot higher than if I post anywhere else.
Anyway, my roommate's cat, my dearest kitty companion, has been having some health issues. We have taken him to the vet multiple times in the last half year and have easily spent over $700 dollars trying to help him, but it has been to no avail. We have made a lot of guesses why he might be sick, and think that it may have something to do with the house we live in.. mold maybe? Could hidden mold be making him this sick and not the other cat that we have?
He is an older cat, 8 or 9 years old, so I expect some health problems, but I want to make sure he is able to live as long and happy of a life as possible. His initial problem was a lot of coughing and sneezing as well as a lot of kitty snot. He's been treated with antibiotics multiple times with varying degrees of success. The last time he was treated, the problem had gotten a bit more severe and he seemed to be losing weight, so he was put on a strong antibiotic. It cleared up the problem for the most part, even though after the dosing was over he once again got a little bit sniffly.. it's not as bad as it was before, but I worry a little bit about it coming back.
The more pressing problem is that he is throwing up FREQUENTLY, and often after he eats. It's a newer problem that started a few months ago. At some point earlier, we had gradually switched him and our other cat over from eating Iams to Premium Edge to try to deal with catbox smell (we had been told that better food makes for less nasty dookie). I also figured he may have an allergy to one of the cheap fillers in the Iams and that his health may improve if he ate something better.
I am not sure if this was the cause of the problem, but the times somewhat coincided. I can't place an exact period of time to when he started throwing up a lot, but it was some time after this change. We tried to feed him wet food as well to see if it might help him eat more and gain some more weight back. My roommate ended up buying him some Fancy Feast since he seemed to really like it and eat a lot of it. He had been throwing up his dry food (Premium Edge) a lot, so we figured maybe wet food would be easier to digest. I tried by mixing to change over from Fancy Feast to a higher quality wet food, but he is very picky and didn't seem to want to eat anything other than the cheap stuff. Could the Fancy Feast be messing with his stomach even more..? He also seems to have diarrhea a lot, and I figure that's probably a problem from the Fancy feast as well.
The two cats have been free fed most of their lives, but lately we have had to start feeding them on a schedule because Domino (the one who throws up) was CONSTANTLY puking and it was getting to be a huge pain to clean up. We thought controlled feeding might help. Also, the other cat, Feral, was getting to be a bit too overweight and could benefit from not being able to eat all day.
The other issue here is that Feral has food complexes and will constantly shove Domino out of the way in order to eat. We have tried to feed him separately in a closed room as well as feeding them together in the same room at the same time..
Roommate bought a bag of Royal Canin (for matrue cats) to transition over to. Domino (pukey cat) seems to REALLY enjoy eating it, but I can't tell if it also makes him throw up, since he has only ever had it in his stomach in conjunction with at least some fancy feast.
Also, he often throws up mostly undigested cat food, but often throws up bile in the morning before he's eaten. One of my concerns is that some of the houseplant eating he has done may have damaged his kidneys... It has only happened a few times, and I've checked the toxicity of those plans for cats and didn't see any red flags, but I am still concerned. He had his kidneys checked during a blood test about 3/4 of a year ago, and when he as x-rayed a few months ago the vet said they looked alright. I would like to get him another blood screen, but the vet bills are getting out of control. I have watched to see if he drinks too much water, but it doesn't really seem to be an issue..
I have wondered if he might be eating too much at once or drinking after eating (which I HAVE seen him do with wet food) which might be causing some of the throwing up..
So far we have tried 2 different dry foods (the second of which he didn't like), multiple kinds of "healthy" wet food that he just refuses to eat, kitty probiotics, calorie boosting gel, different feeding schedules.. I am worried that even though we have been trying to do the right things that we may just be overcomplicating the situation and making it worse. We have no idea why he keeps throwing up and the vets don't seem to be able to help much either. I am frustrated beyond reason and often feel sad when I see ANY cat because I am so worried that he is just going to waste away. IT makes me so sad that he begs for food when he's hungry and then throws it up afterwards :(
My current idea is to wean him off the fancy feast and onto the royal canin as soon as possible.. I would like to have a situation where he is eating MANY times daily, but I think I have to get him a crate or set up some situation where he can eat separately so that his servings aren't eaten by the other cat.
We could really use some advice from someone that has some background or any ideas as to what could be going on. He's pretty skinny right now and it's breaking my heart. Thanks so much in advance for any information, and please feel free to ask questions if it might help you better figure out the problem. I'll respond as best as I can.
Much love from me, my roommate, and Domino http://www.furaffinity.net/view/5762076/

In April of 2012, I found a mangy yet adorable cat on my back porch. He was about eight years old and had been on the streets for some time. I took him home and thought, well, let's fix this one up. His behavior was very similar to what you describe. He would frequently throw up after eating, in the morning before eating, and at times would have the most rancid smelling cat breath and puke you'd ever witness. I thought it would help to change his diet and enlisted the help of my favorite local vet. For a little while, it helped, but even specialized diet cat food didn't do the trick. To cut a long story short, he was back at the vet's office after only six months of inside life. The doc told me that it wasn't due to lack of care; he should have recovered. The real issue was a GI tract deficiency and the symptoms you've described are essentially the same.
The causes of this can vary from feline leukemia to any of a number of complexes that cause a cat's internals to stop working while the body cavity swells up with water or blood. The doc told me that my stray cat was a text book example of these sorts of illnesses.
Keep them happy and comfortable for as long as you can and maybe bring up what I've said with your vet techs.
Hoping for the best.
Good luck!
In quick summary, there are a few things you can consider:
hypoallergenic or limited antigen food (something like duck and pea, venison and pea, or fish and potato)
might need steroids (prednisone)
may have chronic rhinitis (nasal inflammation), or asthma; either could require steroids (prednisone) and/or food change and/or inhaler, and/or an immunomodulator (doxycycline or azithromycin)
Things can be done to treat all of these problems. :)

Listen to this guy!
I remember I had a cat once that used to puke and have diarrhea a lot. I don't remember which brand of food we gave him, but switching from wet food to dry food seemed to help the problem. And he would mostly puke in the morning hours so I wouldn't feed him late at night or until noon the next day, I just figured he had a sensitive stomach or something.
As for your cats though.. hmm.. definately try to seperate them during feeding time. Try weaning him off the Fancy Feast and switching to dry foods. If he's puking and having diarrhea a lot then that sounds like he has a lot of water in his diet, dry food might help. He might also be dehydrated, if he's drinking a lot more water than usual that might be a sign. But he might also be drinking too much too fast and it might make his stomach upset.
If you really think it's a food based problem, the best thing to probably do is call your vet and ask if you can bring them a sample and have your cat tested for any allergens that might be in the food. I think they can tell from stool/vomit samples. It would also tell you if he may have gotten into mold or something as well.
I also googled your cat's symptoms, and I got this http://www.petside.com/symptom-chec.....+149165+149335
I've recently heard of feline asthma, which came to mind when you mentioned sneezing and coughing. It might be a bit pricey, but you can get medication for it.
Try using that website to pin in other symptoms you've noticed, I'm sure it will be very helpful or at least give you some idea what you're up against. Hopefully it's nothing too serious and your kitty will be his fat rollypolly self again soon. <'3
I am not a veterinarian, but I do work in a vets office, so I get to see cases like this often and get to hear their suggestions to the owners.
Some things I would try.
Definitely get him off the fancy feast. It is probably not doing much except going right through him, or coming right back up.
Try switching him to plain boiled chicken breast and plain white rice. It is a bland diet much like they recommend for humans to calm the stomach. You could also ask your vet about plain pumpkin. They have recommended it to me for my dogs upset stomachs.
Have they checked his teeth? Sometimes cats with an abscessed tooth won't chew their food, which can cause them to regurgitate whole chunks of kibble.
They did an xray, but have they recommended an ultrasound? It can be costly, but can tell them if there is a blockage.
Is he pooping and urinating regularly?
It is a good sign that he still wants to eat. And at 8 or 9 he still has plenty of good years left. I would try the chicken nd rice first. After that, slowly wean him onto a sensitive stomach dry food. Science diet makes a good one. Just Just try not to change things to often or too quickly. Changes often take a couple of weeks to happen. You could also look into charity foundations in your area. I know our vet has a charity set up for those who have pets who just need a little help that have a loving home.
Good luck with Domino! He's obviously got can openers that love him!
It sounds like their might be something in the air at your home that the cat is having a hard time dealing with, as felines have a very picky respiratory system.
Some cat's bellies are very sensitive as well. Please be sure to very gradually change his food when you do change it. It's a shock to their system to suddenly change it, causes stomach upset and diarrhea too.
Sounds like either one or the two, only I'm not a vet, only one in training.
Take it very slow with him if you change anything, but watch for irritants, perfume, home good-smelling sprays, cleaning supplies, very strong odors... try to think outside the box as far as things to smell goes, as their noses are stronger than ours. Things that don't bother us or things that we can't smell might be getting at him.
I hope what I have said helps in a way. If there's something I overlooked please let me know. Best of luck to your kitty!! <3
as for food, we order our cat food online, its called AvoDerm. we have four cats, they are all adults age 8+, our oldest Murphy was really not doing well a few eyars back and we were worried we were going to lose him, and the food was recommended for general good health. at first he wouldn't eat it, but after a couple days he got hungry enough that he eventually did and now eats it just fine and he's doing really great for a cranky old man hehe.
If you think wet food might be easier to digest, good wet food is expensive and not all that worth it... just add a little water, or better yet, fish oil[which they make for cats], to the cat food. the omega 3 is very good for them and they looove the flavor.
i hope this helps!

Mold is Unlikely if you, your roommate, and your other cat aren't getting sick.
Allergies are fairly likely, since the symptoms are analogous to a digestive issue.
A Weakened Immune System, perhaps from a past virus, or even his moderate age, could be at play.
I wish I could be of greater help, but I'm in engineering, not Vet Tech. I say take him back to the vet for another check-up, preferabley an X-Ray if you can. Many veterinarians are woefully inept when it comes to treating any animal that isn't a dog.
Best wishes and speedy recovery for you and your cat, Ssirrius!
I'm assuming the vet checked for thyroid and kidney problems? Those are the two most common cat ailments and should be checked for.
Of course, some poor cats just have screwed-up health for no discernable reason.
For litter box smell, I highly recommend World's Best Cat Litter. Almost completely eliminates pee smell. Doesn't do much for doody smell, that still needs to be scooped asap, but it does wonders for pee smell.
The only other thing I know to do is make a homemade bland diet, which usually consists of boiling chicken or turkey and shredding/chopping it with with a little plain white rice. You can use broth from boiling the chicken to help flavor the rice some. If kitty can keep down water and the bland diet, you can try mixing in small amounts of their regular food after that. If your cat can keep down water but not food, see if you can get them to drink pedialyte or something similar for nutrients and calories.
It's possible that he's got a GI issue, is allergic to an ingredient in the regular cat food (A bland diet can sometimes help pinpoint this), or that he's vomited so often his stomach has a hard time doing its job.
My cat who was sick is about 13 or 14 years old now and has been having nasal/diarrhea issues for the past couple years. Clear, runny nose, sometimes congestion, sometimes sneezing up snot, almost chronic diarrhea, etc. I've taken him to the vets more times than I can count and every time, the vet would give me some sort of antibiotic pill and it would be hit-or-miss with whether or not it worked out for him.
There are many reasons why a cat may have congestion or a runny nose, ranging from allergies, from an upper respiratory infection (URI), pneumonia, even feline herpes (although feline herpes is commonly paired with runny eyes and ulcers). Perhaps you could try purchasing some L-Lysine feline supplement and see if that works on his runny nose and sneezing? It's a supplement commonly given to cats suffering from feline herpes, but even if your cat doesn't have it, it might help him out. Also try bringing him into the bathroom with you while you shower, the humidity might help him with his nasal issue temporarily, I do that with my cat when he's got some congestion.
With the vomit problem, your cat and my cat may have the same issue; they like eating super fast. In the morning if the bowl is empty (I know your cat was free feeding) and you walk to the bowl, your cat will get super excited to eat, and he will already start salivating, preparing to digest the food he's going to eat. When he crams that food into his stomach really fast (if he's like my cat, without even chewing it sometimes), it just reacts so fast that it just blows right back up into a neat little puke pile. A handy trick to combat this issue would be to feed him little bits of food one at a time before letting him go at his bowl, that way he can work on digesting the "treats" slowly before tackling an entire bowl of food. I would also suggest to continue feeding them seperately, if Feral keeps bullying Domino out of meals, that might be the reason why he blows up after eating; because he thinks if he doesn't eat as fast as he can, Feral will come by and scoop it all up. The fact that the food he throws up is still in neat little chunks gives me the impression that the problem really does lie with him sucking the food down too fast instead of slowing down and chewing.
I've never heard of "Premium Edge" before so I did a quick Google.. it looks to me like an okay brand of grain-free cat food, but what concerns me is that the cat formulas all contain chicken; it's entirely possible that he has an allergy to chicken, it's actually a common problem in cats and dogs (as is grain allergies). I would advise against Royal Canin/Science Diet/Hills, because it's really no better quality than Ol Roy, Whiskas, Iams, Fancy Feast, etc.. and it's priced so highly because vets sponsor them.
If he is allergic to grains, Iams, or whatever, incorporating Fancy Feast may be the reason why he's throwing up the higher-quality food... and believe it or not, cats become "addicted" to the carb-and-artificial-flavour-filled cheaper brands like Friskies, Whiskas, and Fancy Feast.. it would be like feeding a kid chocolate bars and candy for every meal and then offering them some broccoli on a plate, the kid's gonna throw a fit and not want anything to do with the healthier meal.
When my cat had issues with diarrhea, I switched him from Whiskas/Friskies over to Taste of The Wild and after a little while, the issue has subsided and he's doing fine in that area.
I wish you luck with your cat, I know they can be a pain in the ass when they get sick :(
I think your food brand may play a big part in it. If he is allergic to something in the food, almost all the "grocery store" options are going to contain that thing. When I had money I fed my cats Nutro, and still feel thats a good brand at a price I could afford. A lot of people use Blue Buffalo but I never have. Now I just use purina pro plan urinary tract health.
The food change may help the respiratory issues but you won't know until you try. He could have a deformity that is causing him to be prone to these issues. He could be allergic to something or have seasonal allergies (Dutch has seasonal allergies, he gets seasonal ear infections and acts like a bratty kid with a flu lol). But I don't really know how seasonal allergies work in California.... derp.
I really wish you the best of luck with your cat's health. <3
Mold would cause these issues, but then it would also effect everyone else too. It would be unusual for only one cat to get sick from a mold problem and not anyone else. He could have allergies though. Cats are also just really prone to respiratory infections, and an underlying illness could be compromising his immune system as well.
In regards to the stomach problems:
Is the cat just vomiting, or is there also diarrhea (you did mention a strong smelling litter box)?
My cat who just passed away had Inflammatory Bowel Disease which is something that wouldn't show up in blood work.
Also, my dog had Pancreatitis. That caused him to vomit right after he ate anything, and caused diarrhea as well.
Your cat could also have a food intolerance.
You need to be super careful with the foods you feed your animals. Lots of pet foods are actually not healthy. Reading the ingredients (lots of dry food has the main ingredient of corn, which is just filler and not good for cats) and checking where the food is made is very important (there have been issues with pet food from China). Also, this may be relevant: http://www.fda.gov/AnimalVeterinary...../ucm187218.htm
I do recommend seeing your vet again, and trying to switch to a more natural diet. I feed all my animals Blue Buffalo for a dry food, my cat will get Soulistic as a wet food treat occasionally, and then I make everything else they eat.
Maybe withholding water until an hour or so after providing food may prove beneficial. Giving the food time to digest.
The snot thing I am unsure of. Just make sure his nose and eyes are clean. It might help him relax if he has catnip. I know they kind of, freak out, with catnip, but it also makes them happy and really relaxed.
As for the other cat, I would continue to feed them separately or to watch and make sure Domino gets enough food.
Hope this gets better for you :)
All of your cat's symptomes could be numerous things. Thyroid, diabetes, renal, ect. Even though you did bloodwork a while ago i would definitely do it again because it can change that fast and while things might have been fine then, you could be seeing a lot of changes now.
Sorry, I don't mean to be a downer, but just for the sake of potentially helping to identify the problem with your cat as soon as possible, especially if it is in fact the same thing, I'll offer what insight I can.
First off, it may very well not have anything at all to do with what kind of food is being eaten, nor any houseplants that may have been nibbled on. Coincidentally, in my recent, similar experience it was suggested by my parents that the eating of a plant that was in the house for a while, and WAS a plant considered toxic to cats, was the source of her problems. I had a strong feeling it was not related, and I turned out to be correct. Anyway, It seems that, from what you've said, most of the different kinds of food you've been trying get positive reactions out of him. This may just be because of his desire to try and eat something that he can keep down, and not throw up soon after. With my cat, she seemed to do better with wet food, even if she only nibbled at it a little. I'm no vet or expert or anything by any means, but I personally would settle on one kind of simple, bland, easy to digest food and stop trying other kinds, at least for now.
The fact that he WANTS to eat, and does eat, is a good sign. A very good sign. Definitely make note of any degree of apatite decrease.
A suggestion for how his food is given to him, if its not being done already; keep whatever bowl or dish his food is put in on top of something, like a bit elevated so that it's just below shoulder height ish (for him) With my cat, I learned that having her food bowl just directly on the floor made it harder for her to digest. It was something to do with having to bend her head/neck over/down to eat, trying to swallow in one such position and resulting in vomiting of mostly if not completely undigested food. Keeping the food more leveled with her head/neck helped her to get the food down more easily.
I suppose it might help to share exactly what the condition was that my cat was discovered to be afflicted with, so here's a couple of links;
http://www.cat-health-guide.org/fel.....-lymphoma.html
http://www.veterinarypartner.com/Co.....P=A&A=1446
It took a long time to figure out that this is what she had. Aside from the vet we had been taking her to turning out to be absolute garbage (i wont get started on that) initial blood tests and what not weren't turning up anything, but I knew that didn't mean she was alright.
What ended up identifying the condition in the end was an Abdominal Ultrasound. They aren't always all that cheap, but they can provide a great wealth of perspective on a cats abdominal insides that x rays cannot. If there was going to be one last shot at something you haven't tried yet, to get to the bottom of this issue, I would very strongly suggest getting your cat an abdominal ultrasound. I speak from personal experience when I say that it works, and could very well shed light on your cats problems.
I want to apologize real quick for the likely jumbled and disorganized nature of my post here. I tried my best to focus and make it as understandable as possible, despite being incredibly emotional at this time. I can't describe how hard, heavy and close to home this hits, as it is very much quite similar to what I just went through less than a year ago with my own cat.
Anyway, it might not be much, but I hope maybe something can be taken from my shared experience.
And my deepest, most positive thoughts to you and your cat. I hope so very strongly that you are able to identify the source of his problems, and get him treatment. I hope that it isn't something serious, and that he can continue to live a long, happy life. Just don't give up, there's always a way to find an answer, and finding that answer, while it may end up being painful... its still better than letting it go unknown.
He is a very handsome cat. Looks quite a bit like my Chewy did...

Very best wishes to you and Domino~
Honestly, to me (I am not a vet, just have a dad who is and I have had a lot of experience since I'm trying to get into vet school) it sounds like feline inflammatory bowel disease. He also might have gallbladder disease. My old man cat, Pootie, has both of these diseases and has similar symptoms when he has a flair up. The ultrasound would be able to tell you if Domino has either of these for sure, as well as assess his kidneys and all other internal abdominal organs. An ultrasound should be done by a BOARD CERTIFIED veterinary radiologist, not an internal medicine doctor. I'm not sure where you live, so you might have to go to a specialty clinic or to a vet school to find one, but make sure that the radiologist has DACVR after their name. If it is IBD or gallbladder disease, it should be easily managed with medication.
As far as your food issues go, my cat will only eat Fancy Feast and other kitty "junk food" like Meow Mix. Honestly, if he's eating I'm happy, because he only weighs 6 pounds. Getting the cat calories is more important than trying to get him to eat good food. Maybe once he's feeling better, he'll eat higher quality food. However, at this point, you just want him to eat. Offer him meat based baby food (ham, chicken, etc.), low-sodium tuna, and various wet foods. You just want him to eat. Separating the cats will be very important if your other cat is a bit of a piggy. Even if you just let Domino have one room to himself with his own food and litterbox, it might be necessary until he's better. Think of it being like a kitty hospital room.
I hope that information is helpful. www.ACVR.org is a website where you should be able to find a board-certified radiologist near you.
The food he eats is some science diet - don't know what it is specifically, but the tiny,rounded shape seems to help him.
I'm with everyone else that it's not mold causing this. If this is happening regardless of food type, then it's not the food. Sensitivity only goes so far, and a routine-scarf 'n' barf regardless of what the food is, (and i bet you've tried a whole range of things to keep your cat from eating too fast already) That leaves you with the internals the blame- Anything associated with the whole process is going to be a target, as well as factors affecting it, like hormones and glands come along on the blame-ride. Main common problems starting from the entry to the system are often funky dental work can often cause a cat to lose weight, though they're eating, so that's not it. You say the foods partially digested, so it's making it's way down the throat- so that's not it. But you do say it's barely digested- So it's not residing long enough in the stomach to mush about further- the duration and the frequency of vomiting points that the stomach might be your prime suspect.
Within that thought, we can look at the common problems; Ulcers are frequent, and would cause frequent vomiting. But you're not spotting any blood or curdled blood within the vomit, either meaning it's not ulcers, or it's not exactly ulcers. There are other abnormalities along that same line without having blood in them, that could still be to blame- a tumor in the stomach could cause similar effects without blood, but that's starting to drift towards the "less likely" angle of things. More often than not, issues like this are the common problem.
If it's at least getting partially digested, that means your food is there for at least a small amount of time- a mass would more less cause the food to come right back up like a blockage. Stomachs tend to work like a machines- either you've got a problem with it itself, or more likely, the entry and exit routes of that machine are the blame. I'd honestly pin this down as a stomach issue with the problem being at the tail end pylorus of the stomach. Inflammation, scarring, a tear; an issue of some sort there. an abdominal utlrasound would be useful in that. If it's not that, it's probably an issue with the enzymes in your cat's stomach- deficiency, hormones, that route. Both are very feasible. I'd bet all my money on either or.
I don't think the intestines are much to blame here- If your cat still craps out regular bricks without change in consistency of any sort, that end is still working perfectly fine. If there is some gooey-mushy nastyness, then i'd blame cat IBS. I don't think it's leukemia, while the symptoms are similar (let's be honest, cats throw up when a stiff breeze comes in the room, they'll do it for anything) FeLV and FIV has probably been tested 5 times over with your vet. They check that shit constantly.
Hope the tests are conclusive.
