I have a kitten that I got when he was very young (too young I know) but I got him from my vet at 5 weeks. He is perfectly healthy, eats great, plays like crazy and bonded to my spayed 3 year old female immediately. Just yesterday and today I started noticing a new behaviour though. He will snuggle up to her sometimes, purrs really loudly and seems to be suckling on her belly. She tolerates it quite well and he seems to fall asleep, but I am just curious why he is showing this behaviour now at almost 9 weeks. I do realize that he was way to young when I first got him, but his mom had died, and he never exhibited this behaviour until yesterday, that I noticed. Has anyone ever seen a kitten this old reverting back to suckling? He has perfectly normal and very active behaviour otherwise
