I was wandering around the internet (cause I am bored and have another hour at work...sigh). Anyhow, I found this article on Dogster about orange females tabbies. how rare are female orange tabbies?
First let me say, Utah is female and an orange tabby...
I did laugh at the comment about "no orange cats". I went to a cat show (where I met Teri from Curlz & Swirlz) and the colors that were being tossed around made me smile. I had a friend who breeds Maine Coons and British Shorthairs send me a picture of her female Brit - color blue something something or other. I opened the picture and was "oh, a dilute tortie". :)
And I have within the last couple of years discovered what a "torbie" color cat actually is: a cross between a tabby and a calico (or a tortie, but torbies all have white, so I am not sure how that works, but hey, I didn't make up the word). Anyhow, they are tabby cats that have orange and brown markings with stripes (and are probably female like calicos and torties). Ivy is a torbie:
Of course, you can always make up your own colors...I am all for originality!
