Awww, that's cute

It's been my experience that my male cats have actually been a little more lovey and affectionate with kittens and other cats (well, except of course for the Momma kitties)

I once, years ago, had a male who would 'nurse' a kitten we had, who was also male. He actually did that before he was neutered, and continued to do it after as well.
I have picture of it somewhere that I should look for.
