Siamese and Manx breeds: Where the Siamese Manx cat breed originated

Let’s check out some interesting facts about these two breeds from which the Siamese Manx or Owyhee Bob breed came from. 

Interesting facts about Siamese cats 

The Siamese cat breed is an old breed and it descended from cats born in Siam, now called Thailand. They have lithe bodies, striking blue eyes, and dark-tipped creamy coats. They are sociable, very vocal, and has a low meow called meezer.  Their other personality traits are that they are very smart, playful, loyal, and protective toward their owners. Their life span is more or less 15 years if they are cared for well. They are easy to groom, pet-friendly, and get along well with kids which makes them very good pets. 

Interesting facts about Manx cats 

Like the Siamese cat, the Manx cat is also one of the oldest cat breeds in the world. This breed came from the Isle of Man, an island in the Irish Sea and situated between Ireland and Great Britain. It is originally a shorthair breed but the longhair version is said to be the result of cross-breeding with the Norwegian Forest cat breed. 

The Manx breed is also popular as the “cat with no tail” due to its taillessness caused by genetic mutation. These cats have one dominant mutant gene and one normal gene. This mutant gene that gives the breed its “no tail” characteristic may also cause Manx syndrome, a spina bifida, or birth defect where the spine and spinal cord do not form properly. It causes urinary and fecal incontinence among Manx cats. 

Manx cats have round heads and bodies, round eyes, and round rumps. They have stocky and muscular bodies, their ears have a rocker shape if seen from behind, and they have long hind legs. Males weigh from 10 to 12 pounds while females weigh from 8 to 10 pounds. Their lifespan is 8 to 14 years and comes in various colors like the tabby, tortoiseshell, and calico. 

The breed’s varying degrees of taillessness are the following:

  • rumpy – no tail and instead of a tail all you see is a dimple 
  • rumpy-riser – 1-2 vertebrae and fused at the end of the spine 
  • stumpy – 3-4 vertebrae or short tail 
  • longy –  regular long-tail same as with other breeds  

Manx cats have a sweet personality, very smart, and loyal to their owners. As opposed to the Siamese breed’s low-pitched meow, Manx cats have sweet and trilling meows. They love to snuggle and get along well with small children. These cats are good jumpers, very active, and they have a bunny-hop-like way of running. 

The downside with this breed is that they are prone to various health conditions due to their mutant gene. Aside from the Manx syndrome, these cats are prone to these following health issues:

  • arthritis – inflammation of joints 
  • megacolon – the colon loses motility and becomes larger; cats lose the ability to defecate due to lack of muscles in the tail area 
  • mast cell tumors – abnormal growths in the skin 
  • feline lower urinary tract disease –  the disease may result in bladder stones 
  • intertrigo – bacterial, fungal, or viral infection on the rump fold 
  • corneal dystrophy – it is an inherited condition which affects both eyes
  • genetic nerve deafness
  • obesity 

Conclusion 

The Siamese Manx cat breed is among the experimental cat breeds that combine the best of two breeds, the Siamese and Manx breeds. This breed has unique coloring, very vocal and has blue eyes like the Siamese. It also has a muscular built and short or no-tail characteristic like the Manx. Most of all, this breed is becoming popular among cat enthusiasts because it is very smart and it has a sweet, affectionate, and playful nature that makes them great pets for families with kids.
