Beavis is the grey one. I think that she would have been the runt of the litter had the 3 kittens that followed Butthead did not make it...they were all big.
Butthead is so named because he decided to enter the world tail first instead of head first.
So cute!! I just inherited a baby kitty from my son who just didn't have the stomach for the litter box. He got her for gd and figured if she moved in with me, gd would still see her everyday!!
