Thread: how much?

My little Ginger eats all day long, I give her a 1/4 can of kitten chow 4 times a day and she has dry kitten kibble always available, yet her vet says she is skinny for her age. She weighs 4# 2 oz. She is always looking for food! She will stand in the dog dish and eat their food too! Is this normal?, she does not have worms she had been to the vet and dewormed and received vaccinations. Very happy and spunky kitten.
