Neutered males are often very gentle and caring with kittens. You may want to have a kennel for the new baby, so that they can get acquainted in a safe environment (and to insure that the kitten doesn't get into any trouble or danger when the humans are asleep or out of the house).

Don Juan did a bit of hissing and tail-fluffing when he first met Zerlina, but he also gave her some affectionate licks on her ears.
