Every cat I’ve ever had has come running when I used the can opener. They all thought it was tuna or a can of cat food. Not Romeo. He couldn’t care less. He doesn’t come running when I open the can opener. He refuses to eat canned cat food. But guess what he loves, what gets his interest every time? Sliced american cheese from the deli. We found out accidentally one day. We were making burgers a couple of weeks ago using our small electric grill. We dropped a piece of cheese accidentally and he snagged it right up. Ever since then, every time we open the bag the deli puts the cheese in he comes running. He’ll meow at you as if to ask for some. Does your cat eat or want to eat cheese?
