A fat happy Kitten

Given Leopalorn unlimited raw chicken( trying to give it all so it dont go bad, sharky said three days before fridge chicken go bad, it is a cornish hen so not a full size chicken) didn't give him organ meat( but gave pre-made natures varity madalons that has organ meat in it) just fat,muscle and some SMALL raw bones. Is it normal for a 4 month old kitten to eat like a wolf and then, drunken with tiredness to sleep all day,or most of it?.

Will he get overweight from eating so much? I gave him as much as he wanted.

So far this weekend hes eaten, both wings, both drumsticks, and about half to 1/4 the body? stripped of bones or bone in but VERY small.

The chicken was before I started feeding about 24 oz with bones and everything.
