We did it fam!
I saved up enough that I was able to convince the vet's office to offer me a payment plan with a down payment!
I'll pay the $1700 that I've saved up when I take her in and then $200 a month for 6 months (so don't be afraid to ask if you're thinking about getting a commission!), but she's finally gonna get her baby bladder taken care of! ;_;
Her surgery is this Thursday at 8am so I'll have to keep her in the hall bathroom with a litter box and only water (no food after midnight) tomorrow night. Anyone who reads this, keep us in your thoughts! I'll post an update once she comes home.
