Most breeders cut the tails off of longies, so unless you’re a breeder, you probably won’t encounter a longie.

Males might be somewhat larger than females.

Manx cats have broad faces.

White Manxes might have a softer coat than Manxes of other colors.

Eye color in Manxes varies. Green, hazel, gold, copper, and blue are all common. Some Manxes are odd-eyed (that is, each eye has a different color).

Manxes feel surprisingly heavy when lifted.

If you do have a Manx, you can provide it with a cat tree or cat house so it can have many opportunities to jump and play.

If you observe these symptoms in your cat, contact your vet for a diagnosis.
