Jen,

I know how stressed out one can get in multi-cat households. If you've tried everything from ruling out a UTI, tranquilizers, herbal remedies (Nature's Remedy), then it might be best that Sterling be an only cat. Nature is a funny thing, not funny ha-ha, but funny peculiar. I think everyone at one time had the "pts" thought in their mind at one time (I admit to it as well, but never went through it).

It's not Sterling's fault. Maybe the Humane Society wasn't as honest as they should've been. Do you know if the previous owner turned him in for the same problem???

In any case, I'm keeping my fingers crossed for you and Sterling. If you need to talk, give me a call. I'll PM my number.

(((((((hugs))))))))
