A certain male I live with who shall remain un-named, doesn't often remember to keep the toilet seat down. As a female, I honestly personally couldn't care less if it's up or down, I'm perfectly capable of moving the seat as I need to.
HOWEVER.
In the case of a naughty little kitten, I had to make this as a reminder to keep near the toilet for someone, for WHY we need to keep it shut.

As you can see, my knowledge of toilet anatomy is quite lacking. I'm not intimately familiar with the details of them. I was lacking available reference as I drew this, and thus, it's not quite accurate. At all. OH WELL.
