Cat fussy eater

Male cat about 2 years old.
Very wild.
I started feeding it about 9 months ago.
Will catch a variety of things itself.

I give it a variety of wet cat food.
Go cat.
It likes milk.

But it never seems quite satisified?
Sometimes it is for a few hours.

Doesnt like any human food at all. Of any type.

Just started giving it a 2nd option in dried food to go with the first option that it likes.

I think I may be missing something, but dont know what.

Cat is healthy.
