Mom cat has 3 kittens which LOOK healthy. Two big ones and one a little smaller in size. They are 1 week old. The mom is licking the smallest kitten's fingers and toes and it seems she's biting them. I even heard a crack when she bit the fingers or nails. The mom bit the kitten's hand, and when she did not feel satisfied she flipped the kitten in the air.
But it's like she's not trying to hurt the kitten, it's in the licking process. The kitten is also rising in the air when mom licks her tail. It wasn't like this before. It's as if the mom is licking strongly this time. However, the kitten didn't cry when this was happening, nor when the mom bit her hand. I can see blood on the kitten's fingertips and toes but not leaking. Still I'm worried for the kitten. And the other larger kittens' hands are fine. This is only happening to Avalanche. What can be the cause of this? I don't think the mom is trying to hurt the kitten because if she wanted to she would've bit her tummy or any other part in her. It's the cat's first litter. Help me out.
