Vet recommended to feed my kitten canned food, he is almost 4 months, how much do i feed him in a day?

Question

do I leave it out and just let him eat it, or do I do it in portions?

Answer 1

please never use a microwave... it destroys the nutrition.  Raw food is the best, wet food is mediocre and dry is just wrong.  Wet food does not destroy teeth so long as they are eating raw meating bones to clean and strenghten the teeth.
