While other breeds can be born with a short tail or no tail due to mutations, the Manx is the only breed where the lack of a tail is a defining characteristic.
It's important to note that:
* The Manx comes in different tail lengths. There are "rumpies" (no tail), "stumpies" (very short tail), and "rumpy-risers" (a small stub of a tail).
* The Manx gene can cause spinal problems. This is why responsible breeders carefully select for healthy cats and avoid breeding two tailless cats together.
