Milk is okay for kittens. It's not okay for adult cats; it gives them the runs. I wouldn't give
much of it even to kittens, though.
I find my 13 year old cat likes the meltings from vanilla ice cream. She might like the rest too, but that's for
me.

Doesn't seem to be too much for her. I do
not give her anything with chocolate in it, however. Since she expects the remains from ice cream, that means I mustn't bring chocolate ice cream in the house. :/
