We have very greedy cats. They keep trying to tell us that they don't have enough to eat. So Mum decided to sort out something. She has made boxes, and labelled them all, and now we put their cat food out, all sorted.
They each get a little tin of food for breakfast. They share a tin for lunch, and they get a small tin each for dinner. Plus they have a constantly replenishing bowl of dried food.
No idea a) how Bernie has lost weight and b) they think they are still hungry, but anyway!
