Don't feel bad, I know you love your kitty! We made that mistake with Ron too. He was a poor skinny cat from the pound, so we spoiled and free fed him. All of a sudden, we woke up one day, and he was a BIG fatso! It happened so quickly. Ron doesn't get any treats, he is no longer free fed, and he eats light food. He's still a big cat, but he's lost alot of weight.
