I am leaning toward a problem that is NOT a UTI. The spots I found were more like the spots I found when my Y.Lee (RB) was diagnosed with diabetes........LARGE wet spots, not the dribbles of pee combined with frequent box usage.
The biggest problems are 1) It COULD be all from Jim....and 2) It could be ANOTHER cat with a behavoral problem. But peace of mind is a thing you cannot put a price tag on.
My vet suggested I call the office on THURSDAY to make my appointment as that is the next day she is in to OK the deal with the receptionist. I can only hopt that there is still open time on Monday (my day off) to do this or I may need to wait.
