When I had my cats, I gave them each one teaspoon of canned food in the morning, and a bowl of dry food (Meow Mix) to graze at the rest of the day.
The vet said I gave them too much dry food, but, when I had gotten them, they were both starving, so I had a problem cutting back the Meow Mix. I finally just used a smaller cereal bowl; that trick worked...
They saw a filled bowl and thought it was the same amount.
