As a tailpiece, here's a little story.
My cat had 5 kittens, and as kittens do, as they got older, they got more boisterous. Mum Puss (Topsy) was sitting curled up contentedly infront of the fire. Meanwhile the kittens were having a funny half-hour, chasing each other, shredding my legs etc. They then decided it would be great fun to pounce on Mum. First she gave them a filthy look, stood up, turned round and settled down again. They carried on pouncing on her. Then she turned round very fast and hissed and growled at them. Four out of the five took the hint - Mum didn't want to be annoyed. Topsy curled back down again, but I could see she was irritated by the way the tip of her tail kept flicking. One of the kittens, Poppy decided to push her luck and pounced on Mum's tail. With a loud hiss and a growl, Topsy gave Poppy such a smack round the head that she rolled half way across the living-room. She took the hint after that and left Mum alone. A little later, Mum and kittens were all curled up together purring
We got good homes for four of the kittens and kept Poppy. She and her Mum go out exploring together and where you see one, you always find the other.
Even animals discipline their young.
