Every night at 4:30 my cat Gilligan (my little buddy) gets his soft kitty food for dinner. I lock him in the spare bedroom because the other 2 cats I have like to eat his food. They get their own food, but his must taste better. After a while I noticed I didn't have to let him out of the room anymore because he had figured it out for himself.
So he east until he is full, and then lets his sister Killer have some. But he lets her in when he's ready. I caught it on video.
