The "tailless" cat of the British Isles

The Manx is one of the most recognizable cats in the world: it has no tail.

Origin: Isle of Man (Irish Sea), a small island between England and Ireland.

Characteristic:

  • Ancient natural genetic mutation.
  • Absent or reduced tail.

But: the same mutation can cause serious spinal problems.

Let's see the truth.

Legends:

  • Stories tell of various ways the Manx lost its tail.
  • Reality: natural genetic mutation.

Documentation:

Spread:

  • Worldwide since the 1900s.

The mutation

Gene M (Manx):

  • Dominant.
  • Influences spine development.
  • Shortens or eliminates tail vertebrae.

The 4 tail variants

Rumpy:

  • No tail.
  • "True Manx".

Rumpy Riser:

  • Small "stump" (1-3 vertebrae).

  • Short tail (3-5 cm).

Longy:

  • Almost normal tail (a bit shorter).

Only Rumpy and Rumpy Riser win shows.

The "Manx Syndrome"

Specific health problem:

What it is:

  • Gene M influences not just the tail.
  • Can shorten the entire spine.
  • Serious problems.

Symptoms:

Mild:

  • Difficulty defecating.

Moderate:

  • Urinary/fecal incontinence.
  • Locomotor problems.

Severe:

Frequency

Manx kittens:

  • 20-30% have some degree of "Manx Syndrome".
  • 5-10% severe (sometimes euthanasia).

Identification

Symptoms appear:

  • From 1-4 months of age.
  • Some cases later.

Ethical breeding

Problem:

  • Crossing Manx × Manx (both M/M) = lethal for embryos.
  • Kittens with double M gene die in utero.

Correct practice:

  • Manx × non-Manx (M/m × m/m).
  • Litter 50% Manx, 50% normal.

Responsible breeders:

  • Never Manx × Manx.
  • Selection against severe problems.
  • Orthopedic testing on breeders.

Myths to debunk

Myth 1: "A tailless Manx is 'normal'". False: genetic mutation with consequences.

Myth 2: "All Manx have problems". False: 70-80% are healthy.

Myth 3: "Only safe breeding". True: Manx × Manx litters are dangerous.

Myth 4: "Manx is an easy breed". False: requires care.

Myth 5: "No tail = problem". Variable: depends on severity.

The truth

The Manx is a fascinating but delicate breed:

✅ Unique appearance (tailless).

✅ Affectionate character.

✅ Athletic.

❌ Genetic mutation with risks.

❌ Manx Syndrome in some individuals.

❌ Potential health costs.

Adopt it if:

  • You want a unique breed.
  • Ready for health commitments.
  • Adequate budget.

Don't adopt it if:

  • You’re looking for a "problem-free" cat.
  • You want a "perfect" breed.

Ethical consideration:

  • Breeding Manx has a dilemma: aesthetic beauty vs health.
  • Responsible breeders minimize risks.

Investment: €1,500-3,000 + care.

Benefit: 8-15 years of unique companionship.

And remember: behind the adorable appearance of the tailless cat is a genetic mutation. Treat it with care, seek ethical breeders, be ready for the commitment.

And if you find an adult Manx for adoption (with no known problems): it could be the best choice. A life of joy, confirmed health.
