Why is it unusual for male cats to be calico?
When the calico pattern exists in a male, it’s because the cat has three sex chromosomes: two X, one Y (male). The XXY combination is a genetic rarity that occasionally shows up in cats (people, too). And if both X chromosomes carry the calico blueprint, you’re looking at one rare cat: a male calico.
Do calico cats have health problems?
Some problems associated with Klinefelter’s Syndrome include: Cognitive and developmental issues that can lead to behavioral problems.

Where are the genes located in a calico cat?
In a calico cat, the gene that dictates fur color happens to be located on the X chromosome. As shown on the illustration below, if the X chromosome carrying the gene for black fur gets inactivated, that cell will instead create orange fur.
What does it have to do with a calico cat?
But, what does this have to do with a calico cat? In a calico cat, the gene that dictates fur color happens to be located on the X chromosome. As shown on the illustration below, if the X chromosome carrying the gene for black fur gets inactivated, that cell will instead create orange fur.
Why are tortoiseshell and calico cats only female?
Tortoiseshell and calico cats are almost exclusively female. The reason for this is because the pattern is a result of a differential X chromosome inactivation, and males carry only one copy of the X chromosome. Female cats carry two copies of the X chromosomes in their cells.
Why does a female calico cat have black fur?
Ordinarily, this would mean that an animal inheriting one copy of each gene (genotype X B X b) should have orange fur. Surprisingly, a female cat heterozygous at that locus (X B X b) will not be orange. Instead, her coat will be a patchwork of orange and black, a condition known as tortoiseshell. Why is she not just orange?
