About a week after we started feeding Ivory, we saw this orange tabby in the yard, then feeding at our feeding station. He, too, looks undernourished. We named him Cheddar, and he has been a "regular" from then on. He, also, is standoffish, but appears to have been around people some, because he does not run off. We can watch him feed too.
Ivory started coming around recently and last week I got a closer look and saw that (s)he was very skinny. I immediately decided to feed him/her. She ate everything we left out for her--moist and dry food--that first night and came back in the morning for more. (S)he has been coming a.m. and p.m. every day all week. We can sit out on the patio and watch her eat, and she occasionally looks up at us (with the most beautiful blue eyes). Apparently, she has been around humans and is not a feral cat. Eventually, we hope (s)he'll warm up to us. We are going to try to find a place where we canhave Ivory spayed/neutered. Maybe she can be our outdoor cat. Not sure how Tux would take to having another cat in "his" house.
