What if the kitten doesn't eat if I give it ham sausage?

Cats can't eat ham. The salt content of ham is too high for cats, and the taste buds of cats are not as sensitive as humans, which leads to unconsciously high salt intake, which increases the burden on kidneys and even leads to dry hair and hair loss of cats.

And if a cat grows up eating cat food, it won't eat ham. It doesn't know that ham is food.
