Nope...we've had SOLID orange female cats...both at the feral cat clinic and at the rescue I volunteer at.
All orange cats are male
No, it is possible to have an orange female. Unlike the orange male, who only needs one copy of the O gene to produce an orange coat, the female requires the O to be on both chromosomes. If she has only one O, the resulting coat colour will be calico.
All calico (tortoiseshell) cats are female
No, while the vast majority of calico cats are female, there is the occasional male. However, virtually all of these males are sterile. the calico colour is sex linked. For a cat to be calico it must have two X chromosomes ergo the cat is female. In rare instances however a male calico will be produced. This usually happens because the cat has an extra chromosome. So, instead of him being XY, he is XXY. These cats are known as Kleinfelter males.
* Approximately 1-3,000 calico's are male & out of those only 1-10,000 are fertile.
