Cat breed
Manx
The Manx is a stocky, rounded cat from the Isle of Man, known above all for having no tail or a very short one. It has a gentle personality, is intelligent and very devoted to its people. The lack of a tail, however, is caused by a mutation that can damage the spine, and that is something you need to know before buying.

Temperament
The Manx is a calm, gentle cat that bonds strongly with one or two people in the household. It likes to take part in daily activities, sits in laps and follows family members around. It is intelligent and learns easily, so it has no trouble mastering simple commands or reward-based games. It can also be playful and enjoys games with the family. It gets along well with children, cats and friendly dogs. It likes to “chat” with its owner, but its voice is quiet, more purr and chirp than meow. It values a steady daily routine and handles change, such as moving to a new home, poorly. With strangers it is usually polite, though not effusive. As a rule, it causes few behavior problems as long as it has company and something to do.

Who is the Manx for?
The Manx can suit calm families with children and people who want a gentle, intelligent cat that is devoted to its home. When buying a kitten, choose a breeder who doesn’t mate two tailless cats, uses tailed cats in the breeding program and doesn’t let kittens go before their health has been assessed. If you are not prepared for the risk of neurological problems, choose another breed.

Care and exercise
The short, dense coat with its thick undercoat only needs combing once a week, the longhaired variety several times a week. Because there is no tail, pay special attention to the area around the anus, where feces can stick to the fur. Good-quality food that produces firm stools and regular checks of the area help. Check the skin fold on the rump gently for redness. It is best to buy a kitten from a breeder who keeps the kittens until it is possible to assess whether they show signs of Manx syndrome, which usually appear before four months of age. The Manx enjoys play and a steady routine, and a multi-level cat tree and a daily play session help keep it in good shape.
How much should the Manx eat?The calculator starts from this breed’s typical weight: calories and grams a day.Health and breed-related conditions
The Manx’s taillessness results from a dominant mutation that disrupts the development of the lower spine. Kittens with two copies of the gene usually die before birth, which is why breeders don’t mate two tailless cats. Some cats with one copy develop Manx syndrome, a spinal cord defect resembling spina bifida that leads to problems with the hind legs, urinary and fecal incontinence or persistent constipation. In one study, signs affected about 30% of the Manx cats examined, almost exclusively completely tailless ones. RSPCA Australia also lists rectal prolapse and urinary tract defects. Skin fold dermatitis on the rump and corneal dystrophy have also been described. VCA gives a lifespan of 15–18 years, but cats with a severe form of the syndrome live much shorter lives.
- Manx syndromeA spinal cord defect similar to spina bifida: problems with the hind legs, bladder and bowel; mainly affects completely tailless cats.
- urinary and fecal incontinence, constipationResults of nerve damage in the sacral region; in severe cases the cat lives only a few years.
- lethality in homozygous kittensKittens with two copies of the taillessness gene usually die in the womb.
- skin fold dermatitis on the rumpThe skin fold where the tail would be is prone to inflammation.
- corneal dystrophyThe breed is predisposed to it.
Health tests to ask the breeder about
- neurological exam of kittens before going home (around 4 months of age)
- assessment of bladder and bowel control
- eye exam

Breed history
Tailless cats from the Isle of Man in the Irish Sea were described by sailors as early as the 16th century, and by the early 19th century they were simply called Man cats. The taillessness probably began with a natural mutation in the local shorthaired cat population, which the island’s isolation quickly fixed. The longhaired variety may have come from cats brought by the Vikings. The first, informal breed standard was published in 1903 by Charles Henry Lane. The Manx was among the breeds registered by the CFA from 1906. Today FIFe treats the longhaired variety as a separate breed, the Cymric.
Fun facts
- A single Manx litter can include completely tailless kittens, kittens with a short stump and kittens with a full tail.
- The longhaired Manx probably owes its longer coat to cats brought to the island by the Vikings.
- Only completely tailless Manx cats may compete at CFA shows.
- The first breed standard was published by Charles Henry Lane in 1903.
Frequently asked questions
Do Manx cats suffer from having no tail?
The lack of a tail itself doesn’t hurt, but the gene that causes it disrupts the development of the lower spine. Some cats develop Manx syndrome, with problems in the hind legs, bladder and bowel. It most often affects completely tailless cats and shows up before four months of age.
Are all Manx cats tailless?
No. Manx litters include completely tailless kittens, kittens with a short stump and kittens with an almost normal-length tail. Breeders deliberately use tailed cats, because mating two tailless cats risks kittens dying in the womb.
How big do Manx cats get?
According to the CFA, males average 4.5–5.4 kg and females are a little smaller; older breed descriptions gave 3.5–4.5 kg for females. The Manx has a compact, stocky build, so it feels heavier in your arms than its weight suggests.
How long does a Manx live?
The typical lifespan of the Manx is 15–18 years. Genetics, weight, exercise and regular preventive vet care all make a difference.
