cat treats with cheese?

My cat Carly is only fed dry cat food. I tried to find a cat treat she would like to no avail. She turns her nose up to people food except once in a while she finds a crumb on the kitchen floor. This time it was cheese, and you could tell it was the greatest food in the universe!

Are cats allowed to have cheese? I want to make homemade kitty treats for her, cheese and chicken maybe? Does anyone have any kitty treats recipes? Is there a good list of what to avoid?

Bon Appetit,

Sammy
