just in case

The black cat is coming to my patio door every night. He (?) is very young, I would guess about 10 months. I've stopped chasing him and let them growl and bat through the glass, although that's Sophie and not him. I decided that since that's what you do when you bring another cat into the house I would let it go on, and it's getting better. Now they mainly just look at each other. They're getting adjusted. You know, just in case. :)
