My 5 week old kitten that I just got yesterday may 17th gets mildly aggressive with his bottle when I feed him and I dropped a piece of cooked hamburger last night and when I tried to get it from him he was a ferocious tiger and almost tore apart my arm is he too young to worry about this behavior or how do I properly correct it?

It sounds like he isn't getting enough to eat. Why do you have such a young kitten? He should still be with his mother.

Exactly... they should NOT be separated from their mother for at least 7 weeks.

The people I got him from had him almost weaned so I started him back on the bottle because I agree he should not have been separated I was going to give him 3 bottles a day along with about an 8th of a can of wet food is that not enough

If I'm correct, he should be fed about every 3 hours rather than just 3 times a day.

Like J_9 said, that's not nearly enough. You are starving the poor thing. I'd rip up your arm too.

Ok and I have no clue how much he was getting before I got him he does eat the wet food should I continue to offer it, or wait a week and keep him on just formula

If he's away from his mother, he needs BOTH wet food and formula, but you are going to have to step up on the feedings if you want a happy healthy cat.

Would you feed your human baby only 3 bottles a day? I think not.

He should be gently and carefully bottle fed every three hours -- kitten milk from the pet store, NOT cow's milk (or you'll kill him). He can eat small portions of canned kitten food three to five times a day. And what about during the night? Is someone feeding him then too?

Does he use the litter box correctly?

I will step up feeding and is the amount of wet food OK I give about an 8th of a can 4 times a day

Does the kitten eat it all? What do you do with the leftovers on the plate or in the can?

I fed him at about midnight with the bottle then he slept until about 6 am and I gave home some wet food and then at about 815 he had another bottle he is still learning how to use the litter box

Does he eat all you give him, or are there leftovers on his plate?

I make a full bottle and he eats about a quarter and he finishes the wet food at every feeding

Is this special kitten milk (not cow's milk)? What do you do with leftover milk?

Cats don't gorge themselves like dogs do. Once cats are full, they will stop eating. Give him a little more canned food to see if he is still hungry.

Yes it is kitten milk and I refrigerate the left overs as directed on the container

Do you warm up the milk under warm water from the faucet before you give it to the kitten again?

So give him a little more canned food next time. Okay?

Yes I make sure its very slightly above body temp

And what's happening with the litter box situation?

He hasn't peed anywhere except the box but he has pooped 2ce outside of it one on my blanket and once behind my bedroom door
