I think that sounds fine. Are you going to let him choose when to stop nursing and get a kitten, or will the kitten just show up and the boob access be denied because of your decision? Do you have a backup plan if he decides the kitten wasn't worth the sacrifice? Does the kitten go (where would it go?), and he can have his nursing back, or is it a perm thing no matter what? Does he know that? Can it be a party for him and kitten together. Kitten is big enough to stop nursing and come live with him, and he is done nursing and gets to help take care of the kitten and snuggle it when he wants comfort?
But, I've never weaned a 4 year old. I was done at 2 with both.
