For my cats, Shimmer and Ryker, I will lay some Cheese and pepperoni lunch meat in front of them. I will let them choose which one to eat first. I will do this for 5 to 7 days. My predictions are that Shimmer will eat cheese more often than Ryker. I think Ryker, who loves to steal food off our plates while eating, will head to the meat first. This will be fun to see who enjoys what and if I know my cats as well as I think.
