I have two spayed male cats who have been living together for ca. 1 year. they've progressively been getting along worse with one of the cats bullying the other cat (e.g. biting, pushing him out of whichever place the other cat has chosen to rest in).
he also has started spaying all over the house six months ago and even peed on the carpet, furniture, and our bed. we religiously clean up after him with enzymatic cleaners.
we've taken him to the vet and ended up getting feliway, cat attract litter, urinary tract health cat food, and even anti-depressant drugs. the latter he refused and when we tried to trick him into eating it he wouldn't touch food for a good day in distrust. ironically we had to stop the other cat from eating the same meds.
as you can see we're somewhat exasperated and are not sure what else we can do. we don't want to loose him, but also can't clean up cat pee every other day. help!
