Cat Forum / General Topics / May 2007is my cat a calico?
He is all grey and white with one small spot of brown on his leg. Does that third color make him a calico? (cat newbie) http://members.localnet.com/~pabron/goof003.jpg > He is all grey and white with one small spot of brown on his leg. > Does that third color make him a calico? > > (cat newbie) I don't know for sure, but I have heard that all calico cats are females...... > > [quoted text clipped - 8 lines] > > Very nearly. About 1 in 10,000 cats is a male calico or tortoise shell (if I remember properly). The reason is that callies and torties must have coats of white, black and orange. Black and orange code on the X-chromosome, but not on the same X-chromosome. Therefore, to have a callie or tortie, the cat must have two X-chromosomes, one for black and one for orange. And two X-chromosomes defines a female. But 1 out of 3,000 kittens (again, if I correctly remember the stats) is a male with an extra X-chromosome, i.e., he has two X-chromosomes and one Y-chromosome. If the two X-chromosomes code black and orange respectively, the result will be a male calico or tortoise shell. However, although extremely rare, such cats have no "intrinsic value" to breeders. The abnormal chromosomal makeup renders them sterile, or so I've been told. >>>He is all grey and white with one small spot of brown on his leg. >>>Does that third color make him a calico?

I did however encounter a breeding male (awesome looking cat too) calico male. There were a couple others there that were the sterile "i am confused about my sex" type too. The cat was breeding like a madman and the folks that had him were aware how rare he is and hoping to get a few more. That was in the early '90s though, so he's probably died of old age by now. >> He is all grey and white with one small spot of brown on his leg. >> Does that third color make him a calico?

No, calico refers just to the colors, nothing to do with the sex. >>> He is all grey and white with one small spot of brown on his leg. >>> Does that third color make him a calico? [quoted text clipped - 5 lines] > > No, calico refers just to the colors, nothing to do with the sex. Not true....See: http://en.wikipedia.org/wiki/Calico_cats >>> He is all grey and white with one small spot of brown on his leg. >>> Does that third color make him a calico? [quoted text clipped - 5 lines] > >No, calico refers just to the colors, nothing to do with the sex. That would appear to be true, except that you can't get the red/black/white combination in normal males. It's part of sex linked red tabby complex. BTW, I have three homozygous and one heterozygous red tabbies - two of the homozygous ones are females (quite rare). The hetero is red tabby and white, and his sister is calico.  SignatureT.E.D.

I guess I stand corrected. >>>>> He is all grey and white with one small spot of brown on his leg. >>>>> Does that third color make him a calico? [quoted text clipped - 15 lines] > >I guess I stand corrected. Well, I need to correct some of that. Of course, I have the same problem now that I had then: trying to type across CJ who has placed himself between the keyboard and the edge of the table, with his tail flipping against the keyboard of the other computer. The males are all heterozygous because they have only one copy of the trait. What I was getting at is that one of the males is from a litter where the queen and tom are both red tabby, as are all the kittens. SignatureT.E.D. (tdavis@gearbox.maem.umr.edu) Remove "gearbox.maem" to get real address - that one is dead Hi: My new cat is suppose to be a calico. Her fur is light black, light brown, and white which is all mixed together over most of her body. Her back side is totally light brown. All four paws are white at the bottom. She has two white back legs. Her left leg is striped in light black and grey. (like a tabby) Her right leg is all light brown. Her under side is all white. Her tail is a mix of all the colors, with the last couple inches being black. I think she is ugly. Everyone who sees her, says she is just beautiful. She is a great pet. >Hi: > [quoted text clipped - 21 lines] > >She is a great pet. The three ugliest cats I have known were calicos: two were mostly white and the other was mostly black. My current calico is pretty evenly balanced, though with somewhat more grey/black. She's a calico tabby - all her large color areas are stripped, as is her tail. <http://67.54.246.139:9000/tdavis/cats/03.jan/index.html> shows four of my fifteen cats: Dandy is the red tabby and white, Maryweather is the calico tabby, Ozy is a red tabby color point, and Millie is his apricot long-hair sister.

Some cute cats! my boots looks a lot like maryweather. boots front paws are opposite of maryweather. >He is all grey and white with one small spot of brown on his leg. >Does that third color make him a calico? [quoted text clipped - 4 lines] > > No. Callies and torties are white, black, and orange from top to tail. Calicos have patches of color. Tortoise shells have the three colors blended all over. Neither have tabby markings, which yours has. Of course, I can't discern a patch of brown on any of the limbs from the photo you've supplied. But I've yet to see a calico with a coat like your guy has. >>He is all grey and white with one small spot of brown on his leg. >>Does that third color make him a calico?

Thanks. Calicos have orange, not brown. And the orange patches are distributed all over. > >He is all grey and white with one small spot of brown on his leg. >Does that third color make him a calico? > >(cat newbie) Calicos are female: the pattern is the result of a single copy of the red tabby trait (plus white) in a female - a male would be red tabby and white.
