    Manx

    The tailless cat from the Isle of Man. Manx come in 'rumpy' (no tail), 'rumpy-riser' (a knob), 'stumpy' (short tail) and 'longy' (full tail) varieties — but the breed standard requires the rumpy. The same gene that produces taillessness can cause Manx Syndrome (spinal defects) in ~20% of kittens. Reputable breeders test extensively.

    History & Origin

    The Manx tailless mutation was documented on the Isle of Man in the 1700s and may date back centuries earlier. The breed was one of the original CFA-recognized breeds in 1906.

    Temperament & Personality

    Calm, sweet, dog-like. Manx fetch, walk on harnesses and bond strongly with family.

    Health Watchouts

    Top conditions reported by CFA/TICA parent clubs, AAFP, the Winn Feline Foundation, and the Merck Veterinary Manual. Discuss screening with your vet — especially before breeding or insuring.

    Manx Syndrome

    ~20% of rumpy kittens

    Spinal defects including spina bifida-like bowel/bladder dysfunction. Most affected kittens show symptoms by 4–6 months.

    Screening: Reputable breeders only sell kittens that show no symptoms by 6 months

    Megacolon

    Slight elevation

    Chronic constipation due to spinal nerve issues.

    Screening: Veterinary monitoring

    Periodontal disease

    70%+ of cats by age 3

    Plaque hardens to tartar and inflames gums, leading to tooth loss and bacteremia.

    Screening: Annual oral exam; daily brushing or VOHC-approved dental treats; professional cleaning every 1–2 years

    Obesity

    ≈60% of indoor cats (AAHA)

    Excess weight increases risk of diabetes, arthritis, hepatic lipidosis and shortens lifespan by ~2 years.

    Screening: Monthly body condition score (target 4–5/9); measure all food; structured play 2× daily

    Arthritis

    Late life

    Tailless spine slightly more prone to degenerative changes.

    Screening: Annual senior exam

    Enrichment & Play

    Active and dog-like.

    Choosing a Kitten

    Choose breeders who hold kittens to 16+ weeks to confirm no Manx Syndrome symptoms. Pet-quality kittens $400–$1,000.

    Frequently Asked Questions

    Are tailless Manx cats in pain?

    Most healthy Manx live normal pain-free lives. ~20% develop Manx Syndrome, which can cause incontinence, weakness or spinal problems. Reputable breeders only sell kittens shown to be unaffected by 4–6 months of age.

    Can a Manx have a tail?

    Yes — 'longy' Manx have full tails and 'stumpy' Manx have short tails. Show-quality Manx must be 'rumpy' (tailless), but pet-quality kittens come in all variations.
