My senior cat is free fed. At one point I had to schedule feed him because he was packing on the pounds. But as he is getting older and not keeping the weight on, I free feed him.
Miss Kitty is schedule fed. As soon as she's done eating, I pick up her food and bring it in the house so it doesn't attract other cats, skunks and what have you.
The three younger cats are schedule fed because they're a bunch of piggies. When they were kittens, I free fed them and it was getting costly.
