Me and my cousin Hannah found a kitten that is 5 weeks old we know where its home is I'm just wanting to know what it eats

Milk

Did you just answer your own question? If you did you are wrong.
Cats shouldn't have cows milk, if you give the kitten any milk it should be specially formulated cat milk from the pet store.

At 5 weeks the kitten is perfectly capable of eating cat food. You can find a wide variety of foods at pet stores and even supermarkets, just make sure you buy one that says "kitten" on the can.

Cow's milk will give the kitten diarrhea. Why is the kitten wandering around?
