• Developed in the United States during the 1960s.
• The foundation cat, Yodie, was found on an Arizona Native American reservation.
• Selectively bred to create a distinct breed with a "wild" appearance.
• Genetically unrelated to the Japanese Bobtail.

Genetics:

• Caused by a different, naturally occurring gene than the Manx.
• The gene is not linked to any known spinal or health defects.
• Tail length is typically 1 to 4 inches.
• A flexible, expressive tail is a breed hallmark.

Body Type & Structure

Tail Characteristics

Manx Tail Types:

• Rumpy: No tail vertebrae; a dimple at the base. This is the show-quality standard.
• Rumpy Riser: A small bump or rise of cartilage.
• Stumpy: A short, often kinked or curved tail.
• Longy: A tail near-normal length (cats with this length are considered pet quality).

American Bobtail Tail:

• A naturally short tail, typically one-third to one-half the length of a normal cat's tail.
• Highly flexible; cats often wag or wave their tails expressively.
• Each tail is unique, with no two being exactly alike.

Health Considerations

Manx Syndrome

A Critical Health Concern:

• The Manx gene can, in some cases, cause severe spinal and neurological defects.
• Affects approximately 20% of Rumpy (tailless) Manx cats.
• Symptoms may include:
  • Incontinence (bowel and/or bladder)
  • Hind leg weakness, paralysis, or lack of coordination
  • Spina bifida (incomplete closure of the spinal column)
• Symptoms typically become apparent by 4–6 months of age.
• Responsible breeders perform careful screening and do not breed from affected lines.

American Bobtail Health

A Generally Robust Breed:

• No known genetic health issues are linked to the bobtail gene.
• The breed is considered healthy and robust with a diverse gene pool.
• Requires standard feline health maintenance and regular veterinary check-ups.

Care & Maintenance

Requirements for Both Breeds

• Daily interactive play to satisfy their intelligence and hunting instincts.
• High-quality nutrition appropriate for their age and activity level.
• Annual veterinary check-ups and preventative care.
• Indoor living or safe, supervised outdoor access is strongly recommended due to their strong prey drive.

Breed-Specific Considerations

For the Manx:

• Monitor kittens closely for any signs of Manx syndrome.
• Long-haired varieties (Cymric) require more frequent grooming to prevent matting.
• Weight management is important due to their stocky build.

For the American Bobtail:

• Moderate grooming is needed, especially for long-haired individuals, to maintain their shaggy coat.
• Provide ample active play and puzzle toys to engage their intelligent minds.
• Their adaptability makes them excellent companions for various lifestyles.

Final Thoughts

Both the Manx and American Bobtail offer the unique appeal of a shortened tail coupled with remarkable intelligence and dog-like devotion. The Manx brings ancient charm and a truly tailless silhouette, but requires diligent breeder selection to ensure a healthy kitten. The American Bobtail offers a worry-free genetic profile, striking wild looks, and superb adaptability. Ultimately, both breeds make exceptional, conversation-starting companions for owners looking beyond the ordinary feline.
