My cat Grace is 1 and 1/2 years old, but has been having this problem ever since she was litter box trained just over a year ago. She goes to the bathroom in the litter box no problem, but when she has to pee, instead of squatting, she lifts her butt up and pees all over the wall, or the litter bucket, or the wastebasket, or whatever is next to the litterbox. I don't think it has anything to do with a UTI, since she doesn't pee anywhere in the house, and never exhibits any trouble or discomfort urinating in the litterbox. It's also been going on for over a year. She also doesn't do it if there isn't anything next to the litterbox, but the only way that happens is if I keep it in the middle of the room, and my house just isn't that big. Any ideas as to why it's happening and how to stop her from doing it?? (my other cat doesn't do it, if that matters) Thanks for any input!!
