need advice on: **Kitten bites hard enough to bleed when getting treat.**

not fully sure what i’m suppose to do here.

we have a kitten who is 4 month old and he is very hyper, very normal kitten behavior.

my problem is that no matter what, when he takes treats bites you. not on purpose but like he to excited to get the food and he bites the closet thing aka fingers.

I’ve tried yelling ouch doesn’t really do anything

i’ve tried giving it flat hand but he looks to my finger

he grabs onto my hand and just to hyper and aggressive

advice would be wonderful
