I have a male cat, Robbie, who is now about 2 years old (he was 8 mo. when we got him). He was our first. When we adopted our female, Jasmine, about 3 months later, Robbie started peeing in any sink he could find. Then, about a 8 months later, we added another male who had been a stray and ever since, Robbie pees on the kitchen floor and on the couches. What can we do, short of finding him a new home, to remedy this problem? We have a new baby boy and this is not the kind of environment I want him around. Thank you!
Cats are very territorial and you should try a separate litter box for each cat. If this does not work, talk to your vet about Valium. Good luck, vetcare
