Ok so Luna has the strangest habit i've ever seen in a cat (and all my friends with cats think it's wierd too). When she's really happy and she and I are cuddling, I'm petting her, she's purring like crazy, she goes and starts licking her tummy. More precisely, she kind of suckles on one of her nipples, still purring. She's done this since I got her when she was 1 1/2. now she's 4 1/2 and still does it though not as often. when she was younger, she did it so much the hair around one of her nipples kinda wore away. but then she stopped doing it as much, and the hair grew back. Now she only does it occasionally. Does anyone have any idea why this is? any insight would be helpful.
thanks!:
