My vet says kittens need access to food 24/7 until they are a year old. I have other kitties, and I placed the kitten's food under a box with a hole in it that only baby could get through to keep older (fat) kitties out, and poked holes in the sides and top so light could get in, and made a few length adjustments using double stick tape to the underside of the bowl because smart (fat) kitties could still stick a paw in there and drag the bowl over to their (fat) mouths.
