If there is a place where the other cats can't reach or fit then you could also feed Tiny there and just leave out a bowl of dry food. Some cats like to nibble all day. Aby's are very long thin cats but are very muscular. My Sunny is an Aby mix. I can't free feed any more so I feed my cats 4 small meals a day and I watch them eat so no one steals any one else's food. It took a few days for them to learn the routine but now they know when it's time to eat. Good luck.
