One of my cats is 12 lbs, and the other is 16. They get water and Science Diet, period. The funny part is, I may have to start restricting their feedings rather than free-feeding because our puppy is trying to eat their food. She scrambles over the baby gate easier than the cats and is smaller than them, so other than feeding them on a table or counter (habits I do NOT want to encourage) I can't think of any way to keep their food away from the pup.
The kitties are a little chubby, I admit, but the bigger one is very big-boned and it's mostly muscle.
