Oh, bless his little heart! Maybe even if another cat can't nurse him, if there is some friendly kitty to cuddle with him and bathe him, that might be some help in socializing him. Get something yucky like bitter apple to make his parts taste bad.
And PM hissy, and TNR1 because I really think he is endangering his health with this behavior.
Everything is looking a bit better... I haven't seen his sucking on himself at all since this morning..
I laid them out on my bed this afternoon and red for two hours.. and they were pretty good.. only had to pull the little guy away one or twice.. then he found my bellybutton.. he amused himself with that for quite a bit.. but now it's sore from the tiny teeth that are coming in.. lol
I am calling the vets tomorrow, because he has a bit of really runny poop, and i don't want him getting dehydrated.
That's good to hear. We had a similar situation. Not pretty since while he was doing his business the others would be stimulated to do their own business, if you catch my drift.
We had to pull him apart, got him a stuffed ducky thing and her eventually grew out of it. Good luck.
