Hi new to the boards here but thought I would ask question and see any advice. I have a 2 year old short hair male fixed tabby. About a year ago he peed outside his litter box I took him to vet and it was determined it was behavioral. Was told to try feliway, relocate litter box, give him extra boxes etc. I did all that and every few weeks he would pee somewhere he had peed before (I must not have got all the smell out of carpet) but all the while he was still also peeing in his box. Then I decided to take him back to vet and it was determined he was showing some signs of joint pain in his back so she started him on Dasuquin. That seemed to help but he still occasionally decides to pee outside his box! I’m at my wits end because the vet tells me it’s not medical, it’s behavioral and I cleaned the areas he has went as good as I can with enzyme cleaner. Is it a habit at this point? What else can I try?
