Why Does My Kitten Hate Me?

my kitten absolutely hates me, and she has been sick for a week now. there’s nothing wrong with her, i’ve looked at her eyes and they’re clear. but every time i get near the cage it starts screaming at me to stay away or that something is going on in there! how can i stop this? also when we first got her, my husband put food in the bowl and he said some of it was left over from last night…how many hours did we leave him alone??? please help!!!!
