My cat has started to lick and suckle his sister, he does this on the side of her. She doesn't seem to mind, but when she has had enough she walks away. This has only just started to happen, her fur gets very wet from him. Why does he do this, is it normal, should I try and stop him. Advice please
This happens with young cats that recently have been separated from their mother. In of itself it doesn’t really hurt anything however the cat’s teat can become raw or infected.
You can gently and quietly shoo the cats trying to nurse away from the other cat. The behavior should go away over time.
