  1. There’s been a lot more study into male torties. It used to be thought male torties were caused by a chromosome abnormality and sterile. As a result of recent studies and tissue samples, the main cause is now thought to be chimerism (fused embryos) and a lot of male torties are fertile. There are some cat familes that have two or three generations of tortie males in the pedigree and a very famous male tortie Maine Coon called Pretty Boy Floid who fathered 27 kittens. The recent studies suggest that fertile male torties may be the rule, rather than the exception.

    • This may be way out there, but given that pregnant females can have several male partners for one litter (as each kitten has her/his own sac), does this make the possibility of a chimera more likely in the domestic feline?
