Cat White Spotting Gene

The cat white spotting gene is also called the piebald gene and it is not limited to cats i.e. it is the "white spotting gene". The piebald horse or painted horse is perhaps the classic example of its effect. These are bicolor horses and the bicolor cat is a very well known cat. The calico cat also carries the white spotting gene. The white spotting gene works with any color so you will see black and white cats, tuxedo cats, calico cats (white, orange and black), tabby and white cats, grey and white cats etc. All of then carry the white spotting gene. Solid and white cats are bicolor. The amount of white fur is very variable. The tuxedo black and white cat has a limited amount of white fur on the chest and lower limbs, while the Turkish Van is almost all white with the classic inverted "V" on the forehead and around the ears and a pigmented tail.
