Cleo is SO goshdarn adorable, I swear.
Not true, solid orange tabby females exist, they are just more rare. This is because the gene for orange exists on the X chromosome, and is codominant with other colours when heterozygous. Males cats only have one X chromosome, so they only get one copy of the gene... orange gene = orange cat, non-orange gene = not orange cat. Females have two copies of the X chromosome, so they can have two copies of non-orange, a non-orange and an orange, or both orange genes. Both orange is what you are looking for, and will produce an orange cat, but if genes for white splotches are present they will not be solid. However, solid is entirely possible. If a female cat has one copy of the orange gene and one copy of non-orange, you get a calico or tortie...every orange cat with no white or other colors is a male, just my luck, my favorite color and I can't get males.

That's ok, it's perhaps because it is in my thread. My influence. I am known to produce walls of text in the planted section.
