No but calico females outnumber calico males by anywhere from 300-1 to 2000-1. The reason is that the genes that control feline coat color are found on the X chromosome. Females have two X chromosomes; males have an X and a much smaller Y. (During fertilization, the female contributes an X to the embryo, whereas the male contributes either an X or Y. If it is an X chromosome, the embryo is female; if it's the Y, the result is a male kitten.) To compensate for this imbalance, part of one of the female's X chromosomes, on which the genes for orange, black and white coat color are coded, is inactivated or turned off. Inactivation takes place several days after fertilization when the embryo has grown from a single cell to a cluster of cells. It is a random act as to which X chromosome is inactivated in each cell. In some cases, it might be the gene for white coat color; in other cases, it will be black. This random turning off of genes results in the unique patterning of the calico and tortoiseshell cat.
It is a rare genetic occurrence, but a male calico can result. This cat will have two X chromosomes and a Y chromosome, and will usually be sterile.

not ALL but MOST - it's VERY VERY rare to have male calicos. It's also not true that all ORANGE cats are male - just a majority. And YES calicos do purr - I don't know where that person got that from - all I have ever owned are calico's (all female and all VERY capable of purring) :)

It is a genetic aberration for a tri-colored cat to be male. And it does happen, maybe one in every 20,000 kitten births. The tri-color gene is recessive on the X chromosome. So it takes XX to express that color pattern. XX is female, XY is male. Occasionally a male (human too) is born with an extra chromosome XXY. That male can be calico or tortoiseshell.

Yes, mostly. There are two X chromosomes and roughly 99%
of calicos are female. The rare XXY trisomy appears male but is
sterile.

I have been told this for many years & I believe it....I've never seen or heard of a male calico. However, in this ever changing world we live in, the anwers "never", "impossible", "absolutely" & "always" can sometimes be too rigid.

usually yes, it is very rare to find a male calico, but I am sure they do exist.
