Cats with the heterozygous genotype (Mm) show severely shortened tail length, ranging from taillessness to a partial, stumpy tail. [3] Some Manx cats die before 12 months old and exhibit skeletal and organ defects. Because it was discovered in naturally occurring populations of cats, the Manx gene could confer some kind of selective advantage ...
A longy white Manx female. Although tail suppression (or tail length variety) is not the sole characteristic feature of the breed, [5] the chief defining one of the Manx cat is its absence of a tail to having a tail of long length, or tail of any length between the two extremes. [23]
The main strength of the tail suspension test is its predictive validity– performance on the test can be altered by drugs that improve depressive symptoms in people. Specifically, if antidepressant agents are administered before the test, the animal will struggle for a longer period of time than if not and exhibit more escape behaviors. [1]

The Manx is one of the founding breeds in the Cats Fancier Association, which was founded in 1906." That didn't tell me a whole lot about the cat, so I headed out to find more. What I found is ...
The Mekong Bobtail—a colorpoint cat breed with a bobbed tail. More than one gene is responsible for tail suppression in cats; research is incomplete, but it is known that the Japanese Bobtail and related breeds have a different mutation from that found in the Manx and its derivatives. American Bobtail
Another example of a recessive lethal allele occurs in the Manx cat. Manx cats possess a heterozygous mutation resulting in a shortened or missing tail. Crosses of two heterozygous Manx cats result in two-thirds of surviving offspring displaying the heterozygous shortened tail phenotype, and one-third of surviving offspring of normal tail ...
The Manx cat (/ ˈ m æ ŋ k s /, in earlier times often spelled Manks) is a breed of domestic cat (Felis catus) originating on the Isle of Man, with a mutation that shortens the tail. Many Manx have a small stub of a tail, but Manx cats are best known as being entirely tailless; this is the most distinguishing characteristic of the breed ...
