I used to leave salmon skin out for a cat named Keisha that roamed the condo complex. She was a homely combination of mottled brown and black and had a fierce attitude. She tolerated only a brief petting and then she would hiss to get you to back off. I liked that about her. That was about 30 years ago.

Most recently we got a visit from "Bailey" at our new location. He's a gregarious orange and white tabby very much like our own. He was attracted by freshly cooked salmon.
We found out that he lives two houses away, is nearly 20 years old and has cancer. So we keep an eye out for him. We don't put out food for cats, although we have a bird feeder, which attracts birds, rodents and bears.

My wife is a cat person. I'm more into bugs and things. Give me Katydids, Butterflies and (believe it or not) bees, wasps and hornets.
