A 16 week old kitten should be eating 1/4 to 1/3 of a cup per day, and that amount will gradually increase to 2-3 cups in the next 4 weeks.
Should I feed my cat wet or dry food?
You should give your cat either canned or raw food so they can choose what they want. If you do not provide them with water it might cause dehydration, which is dangerous for any animal. Also when you start feeding raw meaty bones, such as chicken necks and backs, this may cause choking hazards due to the size of these long pieces.
