Getting him a buddy, advice?

Hello! This is my Severus!! He’s a silly little guy, he’s about 10 or 11 months old, and we are thinking of getting him a buddy!! I thought I’d ask if anyone has any recommendations of what kind of cat to keep an eye out for? I didn’t know if there was a specific kind of cat that especially pairs well with a tuxedo, or if we should just get another tuxedo. Or if it would be better to get him a female buddy or male buddy. All advice welcome!!! ❤️
