Boy, I thought I had problems w/pee cats. Guess not after reading all these posts. And someone (I can't recall who) said that there were maybe 1 or 2 incidents a week! Yikes! I don't feel so bad now. Since I found Clomicalm there have been no incidents. I know what you're thinking, that I just don't know where they occurred. And you could be right. But I have the nose for sniffing out pee. I think we all have acquired that lovely talent since taking in furkids. And my house is small, only 1800 sq. ft. plus the enclosed patio. If there's pee, I smell it. And everyone who comes into my house, even workers, say that you can't even tell I have one cat, let alone 7. I feel for you, I really do, because when Specs was peeing, I was ready to toss him out the window, I'd get so angry. But then he'd look up at me w/those Emmett Kelley eyes of his and his furry butt was saved. I sure hope you can get some relief from this problem. I know how frustrating it is, believe me.
