Re: How Long After Spaying does Mom Still Have Milk?
Mom may have already dried out and they're "nursing" out of comfort rather than for food. I know my old kitten, Alice, comfort nursed off my dogs (one who never had a litter and one who had her last litter probably a year before that (before I got her) so neither were producing milk. If mom was annoyed by it she'd let the kittens know so it's probably comforting for her as well.
Mommy to Justice, Emily & Isabella (humans), Scarlett & Sasha (doggies)and Rosalie & Zoey (kitties).
