We have 5 baby fur-babies at our house and a mama fur-baby, too. This one makes me think of them. They are just starting to play (- fight) with each other. They seem to lay on each other and what ever is close to a mouth - an ear, a paw, a tail, a tummy, gets bitten! They are maturing so quickly, but each at a different rate! If someone gets pushed off of the mama's tit, then the one pushed off does a windmill on it's sibling, usually on the face or top of it's head. And they don't pull their sharp little claws in yet! I watched one run for 2 gallops one day, then run for about 4 gallops the next day.
