I am not believing that Sterling's little pee-ing problem is all behavioral........not yet. Even though his follow-up urinalysis shows his UTI is much improved, I STILL believe in my heart that there is something wrong with him OTHER than jealousy. It's just a hunch. So on Monday I will be asking the vet what OTHER medical problems could cause this behavior and what OTHER tests we can run to make CERTAIN that he is not ill. I just have to know why he would be territorial NOW when he hasn't been for 3 years prior. After all, I brought cats in to this house since he was adopted and never noticed a problem. I could be grasping at straws, but what if he IS sick and I just assumed it was behavioral?
