I'm writing this on behalf of a friend whose young kitty has been having some litter box issues. Now I don't know every little thing about this cat, but from what I do know, she's relatively young (no older than 3 years, I'd say) and spayed with no prior history of health issues. A couple months ago, my buddy talked about Kitty having bloody urine, so he took her to the vet where she was diagnosed with a UTI and medicated. Kitty continues to pee outside her box and on the furniture and floors, and her urine is still tinged with blood. She doesn't seem to be in pain. Does this mean she doesn't have a UTI, or maybe she has a particularly resistant infection? I think she's been treated for a UTI at least twice already. I know "go to the vet" is the best advice to give and he knows that, but I'd like to ask what folks here might suggest for other possible tests or causes of this ongoing bloody urine? Is it normal for urinary tract infections to be so resistant to treatment? Kitty also has a clean litter box and everything and is indoor-only, if that helps.
