Orange Cats Usually Male. Orange tabby cats are about 80/20 male to female. If orange cats are usually male, and both black and orange are sex linked, does that mean most black cats are usually male too?
Is the same thing true for orange tabby (marmalade) cats? Although orange tabby cats are primarily male, female orange tabbies do exist in a ratio of about 80 percent male to 20 percent female, according to arnold plotnick, dvm. Up to 80% of orange cats are male and nobody knows why.
Ginger cats are more likely to be male than female.
Fun ginger tabby cat coat fact: The gene that codes for orange fur is on the x chromosome. Sometimes a genetic mutation occurs where a cat is xxy and will appear male, and can be calico (because it has two x's) for a cat to have orange/cream and black. This certainly seems to point to some genetic link between sex and coat markings, although veterinarians and researchers still haven’t seemed to pinpoint the exact factors.
