Some Manx cats have no tail at all, and others have a little short tail. If you breed two Manx cats, you will get a litter of kittens with several different tail lengths. And if you breed a Manx cat to a regular cat, you will get some Manx kittens and some regular kittens.
Here are the names for different lengths of Manx tails:
Riser or rumpy riser -- the cat has just a bump of cartilage under the fur.
Stumpy -- there is a partial tail of fused vertebrae, up to 1" long.
Stubby -- with a short tail of non-fused bones, up to half the length of a regular cat tail.
Longy, tailed, or taily -- a cat with a tail that is half- to full-length.
I think we can all agree that these are really funny-sounding names! They make me want to giggle, just reading them. But now that I know what the categories are, I can tell you how our little Manx rescue kittens fit into them: Jeeves is a rumpy, Janey is a stubby, and Jilly is also a stubby. This means that only Jeeves could be entered in a cat show as a Manx , because the Manx class is only for rumpies, risers, and stumpies. Stubby and Longy Manx cats have to go in the "Any Other Variety" class. But of course, Jeeves couldn't really be in a cat show because he doesn't have any registration papers.
Manxes have round heads, long necks, and large eyes. They can be short-haired or long-haired, but they all have a double-layered coat. The most usual colors are tabby, tortoiseshell, calico, and solid colors. A long-haired Manx is called a Cymric.
Anyway, now that I have told you all about Manx cats, I will also tell you that I was shocked to learn that not all tailless cats are Manx cats. This is because the same gene that makes Manx cats be tailless can mutate in any kind of cat, and then one or more kittens are born without tails. This type of cat is called a Domestic Tailless Cat. We can't call it a Manx because there is no way to prove that its ancestors came from the Isle of Man. But I'm sure that our kittens are real, true Manx kitties. We just need to take the time to trace their family tree back a little ways!
