Does Scourge have a mate or kits?

Probably not because he is sort of young and he is too cruel to have a mate or kits.

-------------------------

There is the possibility. The books never told how old he was, and he acted like an adult, even though he was small. Cats can breed at very young ages anyway. Tigerstar had kits, so there is always a possibility that Scourge had a mate and kits. Also, in the manga, a cat that looks very feminine says "that was amazing", followed with "Thank you, Thank you so much, you've saved us, you've saved our lives ... what's your name?" and Scourge is looking at her in a way that might be considered like he likes her. A second time, when the forest cats attacked the lone female- who had very similar markings-, Scourge tells the forest cat to "leave HER alone and get out", which indicates that the cat is a she-cat.

I believe that Scourge and this unnamed she-cat are mates.
