Manx syndrome
The gene that takes away the tail can also make the spine too short. Then the nerves to the hind legs, bladder and bowel can be affected. It usually shows before the kitten is six months old. It is mostly seen in tailless cats; in one old study about 3 in 10 Manx had it. There are no separate figures for the Cymric.
How it is found: No test predicts it, though there is a DNA test for the tail gene. Breeders never mate two tailless cats and use tailed cats. Do not choose a kitten that walks stiffly or hops like a rabbit.
