Welcome to Pet Talk! You've come to the right place for information and most definitely for encouragement.

I have a few cats who did inappropriate urinating on occasion. They're on Clomicalm and it's been a godsend; no episodes since starting them on it. I've recommended it several times to people here on PT. You may have to play w/the dosage until you get it right but it doesn't take much. My cats get only 5 mg. at night before bed and they show no side effects whatsoever. To ease your boyfriend's mind, they are not doped up at all and they have not demonstrated any change in personality. They get blood work done once a year just to be sure that all is well. I'm pleased that your vet recommended it because I'm quite an advocate of it. As for not covering up his mess, some cats just don't. My 18 year old blackie Boo doesn't and never has. I have another Maine Coon cat, Specs, who is just the opposite and digs to China to cover.

One thing, though: you're not moving the litter box from place to place, are you? Since Clyde has been through a lot of change w/you being the third family he's lived with, if you've moved his litter box, that could add to his stress. Cats don't like change much and this could be part of the problem, if you've done it, that is. Just a thought. So your boyfriend could be right about Clyde having to adjust to his new home, if you can be patient enough to wait it out and see.

Good luck and please keep us updated. We'd love to see some photos of Clyde when you have the time.
