The Manx is a medium-sized tailless cat originating on the Isle of Man in the Irish Sea. The breed's defining feature — the missing tail — comes from a natural mutation that fixed in the isolated island population centuries ago. The Manx is also a robust, intelligent, dog-like cat with a playful temperament and a unique "bunny hop" gait produced by longer hind legs.
The Manx mutation arose on the Isle of Man, where the island's geographic isolation locked in the genetic trait centuries ago. Records of tailless cats on the island go back at least to the early 1800s.
The Manx was one of the earliest pedigreed cat breeds, recognised at the first British cat show in 1871. CFA recognition came in 1906. The breed is the national symbol of the Isle of Man.
Medium-sized, round, with a partially or fully missing tail. Adults weigh 3.5–5.5 kg (8–12 lb).
Key features:
Calm, intelligent, dog-like. The Manx is famously friendly — affectionate with family, tolerant of children, polite with strangers. The breed bonds strongly and is often described as "more dog than cat" — many learn fetch, walk on harnesses, and follow owners constantly.
Manx: weekly brushing. Cymric: 2–3 times weekly.
Clean ears monthly. Trim claws every 2 weeks. Brush teeth several times weekly.
Moderate-high. Provide climbing structures and interactive play. The Manx is athletic despite the lack of tail.
Average lifespan is 8–14 years.
The defining concern is Manx syndrome — the same gene that produces taillessness causes spinal cord, nerve, and pelvic abnormalities to varying degrees. Severe cases produce incontinence, hind-leg paralysis, and digestive issues; these usually manifest by 6 months.
Homozygous Manx kittens (two copies of the gene) die in utero — every Manx is heterozygous. Reputable breeders never breed Rumpy × Rumpy, monitor kittens for early signs, and openly discuss the welfare implications.
Other concerns:
50–80 g per day. High-fibre diets help if megacolon develops.
Indoor-only is safest given potential nerve issues.
Pros
Cons
Not suited for owners uncomfortable with the breed's health welfare issues.
Are all Manx tailless? No. The breed has four tail categories — Rumpy (no tail) to Longy (nearly full tail). Show-quality Manx are typically Rumpy or Rumpy-Riser.
What is Manx syndrome? A collection of spinal and nerve abnormalities caused by the same gene that produces taillessness. Severity varies from undetectable to severe. Affected cats may have incontinence, paralysis, or megacolon.
Why do they hop like rabbits? The longer hind legs produce a distinctive bouncing gait. Whether they "hop" varies by individual — some look almost normal, others very rabbit-like.
How long do they live? 8–14 years. Affected cats may live shorter; unaffected Manx live typical cat lifespans.
Are they hypoallergenic? No.

"A cat with no tail. Not docked, not lost — born without one, by a spontaneous mutation that became fixed on a small island in the Irish Sea. The Manx cat — from the Isle of Man — is one of the oldest natural breeds in the world. Compact, rounded, friendly, and famously dog-like. Today: the island origin, the temperament, the very real health considerations, training, mistakes, and whether the Manx is right for you."
"Tailless cats appear in records from the Isle of Man going back at least three hundred years. The genetic mutation — a dominant gene affecting the spine — likely arose once on the small island and propagated through generations of isolation. Manx folklore includes various origin myths — Noah's Ark, Spanish Armada survivors, Viking trade cats — but genetic evidence simply shows a long-isolated island population with a fixed dominant mutation. Modern Manx breeding is careful: two copies of the Manx gene are lethal in utero, so all live Manx cats are heterozygous. Manx-to-Manx breedings produce roughly two-thirds tailless kittens to one-third tailed (genetic carriers). Manx tail lengths form a spectrum: 'rumpy' (no tail), 'rumpy riser' (small bump), 'stumpy' (short partial tail), 'longy' (near-normal). All are pedigree Manx. CFA accepted the breed in 1906."
"Manx cats are intelligent, playful, affectionate, and remarkably dog-like. They fetch. They follow. They greet visitors. They learn names quickly. Many are described as 'one-person' cats but bond strongly with the whole family. Voice is moderate. Chirps and trills. Quieter than Oriental breeds. Bonding is intense. Manx cats genuinely engage as companions. Energy is moderate to high. The breed loves to play, climb, and explore. Intelligence is exceptional for problem-solving and learning. With other animals — generally good. Manx cats pair with friendly dogs and respectful pets. They are famous hunters. Working farm cats by ancestry."
"Two coat types: shorthaired Manx and longhaired Cymric (some registries treat the Cymric as a separate breed). Shorthair: weekly brushing with a rubber mitt. Bath every three months. Cymric longhair: twice-weekly brushing with metal comb. Bath every two months. Daily check of the rear end. Manx without tails have less protection for the anal area and can develop hygiene problems. Wipe gently if needed. Brush hindquarter fur regularly. Nails fortnightly. Teeth daily. Enrichment: cat trees, puzzle feeders, daily play. Indoor or supervised outdoor. Many Manx make excellent indoor cats. Litter: standard. Some Manx with spinal issues may need lower-sided boxes."
"Lifespan eleven to fourteen years. The major breed concern: Manx syndrome. A spectrum of spinal defects associated with the tailless gene. Severity ranges from no signs at all to severe problems with bladder control, bowel function, hind-limb weakness, and arthritis. Most pedigreed Manx kittens are observed by the breeder for three to four months before sale to identify any Manx syndrome signs. Symptomatic kittens are usually placed in pet homes with full disclosure or kept by the breeder. Other concerns: Arthritis in middle age — common, especially in 'rumpy' types. Corneal dystrophy — occasional. Otherwise the breed is moderately healthy with attentive monitoring. Always buy from a breeder who waits four months before placement and openly discusses the Manx syndrome spectrum."
"Manx are among the most trainable cats. They learn fast and engage with people. Targets: name, recall, sit, fetch, harness wear, tricks. Leash training works well. Litter solved by the breeder. Scratching: provide tall sisal posts. Handling tolerance is excellent."
"Mistake one: buying from breeders who place kittens too young. Manx syndrome can be missed in kittens under four months. How to avoid: only buy from breeders who keep kittens to sixteen weeks minimum. Mistake two: ignoring rear-end hygiene. Without a tail, the anal area needs occasional help. How to avoid: daily check. Wipe gently as needed. Trim long fur around the area. Mistake three: assuming all Manx are tailless. Buying a 'longy' Manx expecting a 'rumpy' or vice versa. How to avoid: discuss tail type with the breeder. All tail lengths are pedigree."
"Checklist: You want a dog-like, intelligent, playful cat. You can buy from a reputable breeder who keeps kittens to sixteen weeks. You can manage occasional rear-end hygiene. You can budget for arthritis care in middle age. You want a unique-looking breed. Tick four — the Manx is wonderful. If you want a low-risk shorthair, choose a British Shorthair."
