The cat pees on our shoes and around one area of our house. We recent moved into a new place and I wonder if another animal was in the house before we moved in and she smells the other animal's urine. I don't think I could take any better care of her.
I've given her prescription food that cost $40 a bag. I've tried soft foods, hard foods, soft foods mixed with dry foods, and I've tried about 10 different brands and types. She seems to do pretty well with a lamb based food, and if I trim her hair she does not throw up as much.
Another thing I should mention is that she throws up the most in the summer months. During the winter it is much less frequent.
