I'm afraid if I take them from free feeding to timed feedings, we'll be getting woken up on the weekends, or a feeding will be forgotten, or they'll take to gorging themselves on food, since there's three cats. They're well-behaved enough right now with them all taking turns to eat at their pleasure, and they mostly all graze, even the fat one. I'm going to try puzzle feeders next, because even a hanging toy with catnip hasn't fully enticed the fat one to exercise (she lays on the floor and bats it
)
