I free feed my three Nutro Complete Care Weight Management Formula with a little bit of Felidae mixed in. They usually don't even finish all of their food. Since Cirrus is only 9 months old I know he needs to eat more often than Sunny and Storm do. I'll change in the future if I run into a problem but for now everything is fine. My RB Pepper had a problem with overeating but none of my current cats seem to do this.
