Japanese bobtail cats are not the only felines that have abbreviated or missing tails.The Manx cat is another somewhat "tail-less" breed, although kittens from the same litter may vary from having no tails at all, to full ones. Because the original breeding population of these cats was quite limited, the gene mutation that causes the abbreviated tails is also responsible for a number of health problems, including spina bifida and pelvic malformations.The American Bobtail cat is still being developed, and breeders are striving to establish felines with tails half the length of ordinary cats. |
