Hello, I just got my cats and they are a boy and girl from the same liter. I just wanted to know do brother and sister mate because they are only 5months and the brother just lickes her ears and leaves her alone. I think that is good but she is just making sounds and her butt is up and tail and she wont stop..somebody help
Answer Yes they can mate. In the wild the litter would go off to find new territory to stop this happening. Now is certainly the time to think about getting them both neutered as it will stop things like yowling, spraying etc.
