I only remember one other kitten I had/have doing this, I still have her and she is super bonded to me. Anyway, a couple of the current kittens I have been raising started curling their tail around my fingers or arm while I'm holding or cuddling them the past few weeks (they are about 12 week old now). I think it's a sign of friendship, like cats intertwining tails, but just curious what other people's thoughts on it are, and how common it is, not finding much online about it.
