6 INTERESTING facts about tortoiseshell/calico cats {none like "Most of them are female"}
1. Male calico cats are generally sterile
2.Like most highly developed animals, the female cats have two 'X' chromosomes (represented as XX), whereas the males have a single 'X' and a single 'Y' chromosomes (represented as XY). The X chromosome is responsible for both the black and orange coat color. The white color is coded by another gene.
3. Male cats, with genetic aberration having XXY chromosomes can express calico and/or tortoiseshell color combination. Over here, like in females, the two X chromosomes express the three colors, responsible for the calico color coat. Thus, male cats have calico color combination very rarely. This sex chromosome disorder in cats is similar to Klinefelter's syndrome or XXY Syndrome in humans.
4. Calico cats were announced as an official state cat by the state of Maryland on October 1, 2001, due to their distinctive color combination of white, black and orange, which is similar to the state bird (Baltimore Orion) and state insect (Baltimore Checkerspot butterfly). Unlike the usual calico coat combination (white, black and orange), if the coat color of a cat has patches of white, blue and cream, then the cat is known as muted calico.
5. In some cultures they are believed to bring good fortune.
6. Calico is technically not a breed.
