Animal behaviorist Sophia Yin, DVM, recently answered a San Francisco Chronicle reader’s question regarding a kitty with litter box issues.
The question: We have a 15-year-old female cat and her 10-year-old daughter. The younger one urinates outside her box, mostly on the tile floor of our bathroom, at least twice a day. She also used to spray the walls and floor, but no longer does that. The cats have two litter boxes (one is electronic), and both are cleaned regularly. The vet said there is nothing physically wrong with her. We’ve tried quality litter, clumping litter and cheap litter. Makes no difference. Why does she continue to do this?
For the answer: Why does our cat urinate outside the box? (SF Gate)
