My last two cats were free fed all their lives. I learned early it wasn't going to work with these two. They were eating constantly so they are on a feeding schedule. I've always called them with "OK kittens LETS GO!" They also know "small snack" I have to watch it sometimes because they really recognize these words. The other day I said "kittens doing ok" and they flew toward their eating area when it wasn't time to eat. They'll always be kittens to me. They are 6 now.
