I know how you feel about having to have her confined to one room by herself all the time. I am dealing with that with my "loaner" cat, G. But when I let him out him and Paizly get into it and he chases her under the bed or chair (he's too big to fit). I don't want him stressing out the resident of the house so he gets put back in his room. Paizly doesn't seem too stressed with the occasional encounters with him so we will continue as is.

I am glad that your house is becoming pee-free. It sounds like Cami is enjoying her one on one time and being alone for the most part. What ever works, right?
