Why Do Manx Cats Have No Tail

The Manx cat’s lack of tail is the result of a genetic mutation possibly caused by inbreeding among the small population of British Shorthairs on the Isle of Man. The true or ‘rumpy’ Manx has only a small hollow where the tail would have been, although cats with residual tails are born.

Are Manx cats rare?

Manx cats are not necessarily rare. However, they are definitely not as common as other breeds, such as the American Shorthair or the Scottish Fold. On the other hand, an all-white Manx is quite a rare find.

Do all Manx cats have Manx Syndrome?

All Manx cats are heterozygous for the Manx gene (i.e. Mm), which means they have one mutant M gene and one normal m gene. The mutant M gene is dominant to the normal m gene (Long 2006).
