Only female cats can be tortoiseshell because the coat colour gene is sex-linked & in all cells one X chromosome becomes inactive. Each allele is either black or orange & because the process is random it results in orange and black patches across the body. http://ift.tt/1NSS0uT
Tortie Cats!!! I have one and will never not have a Tortie, they are the most loving animal ever!!! This one is not mine but similar.... I love their coloring too!!! If you want a lap cat who loves to play too I HIGHLY recommend getting a Tortie!!
