All colours

Manx are totally round and have Cobby body types. Their heads are round, with round cheeks and big round, barely angled eyes. They have short backs, which curve from their shoulders to their rumps. Their strong hind legs are longer than their front legs, and their roundness is further accentuated by their lack of a tail. 

This is the case at least, for the most desirable type of Manx. The different cat associations divide the breed into 4 or 5 subgroups according to the length of their tails. According to the LOOF (the French Cat Federation), the 4 subgroups are:

• The Rumpy: No caudal nor sacral vertebrae and thus the Rumpy has no tail at all! There is a small groove where a tail would normally be found. 
• The Riser (or Rumpy-Riser): 1 to 3 sacral vertebrae and a small "bump" of cartilage where the tail normally is normally found. 
• The Stumpy: 1 to 3 caudal vertebrae which give the Stumpy a short tail.
• The Longy: long, sometimes even totally normal tail.

They are extremely kind and loving in nature.

Manx are excellent hunters, so it's no wonder they love to play! Manx adore daily play sessions where they can show off their talents.

Despite their playful nature, Manx are very adaptable and know how to relax and be calm.

Manx are very intelligent, and it is said that they can learn tricks almost effortlessly ... such as opening doors and switching on taps.

Generally it takes a Manx a little more time before fully trusting a newcomer. To start with, respect and understanding are required.

They prefer to be in the company of humans, or even of other 4-legged friends, rather than to be left on their own.

Manx rarely meow, and generally prefer to coo.

Their powerful hind legs and bunny-esque physiques make them prodigious jumpers and capable of rapid acceleration. They will not hesitate to show off these talents.

In general, they’re too attached to their humans to run away, but there are always exceptions.

These cats have big appetites and are quite greedy which means they gain weight easily!

These tailless cats are sociable and if left the time and opportunity, are able to get on with other cats.

Introduced to each other correctly, a beautiful relationship can be born between Manx and dogs.

With a little supervision, these big, whiskered teddy bears can be very patient with children.

By ensuring that they have enough exercise time, Manx can be perfect companion for an elderly person, especially when the latter gives them lots of attention.

Despite their thick coat and dense undercoats, they only lose a reasonably manageable amount of hair.

After taking a long time to mature and grow, Manx also generally live long lives, reaching fifteen years of age on average.

This "tailless cat" is generally very robust, even if you may think otherwise!

This cat has a genetic predisposition to being overweight.

• Manx Syndrome: when the mutated gene shortens the spine too much, severe abnormalities appear in the spine and spinal cord, such as spina bifida, but also in the bladder, intestines and hind legs ... Manx that suffer from this disease have significantly shortened life expectancies (5 years max).
• Megacolon: With this disease, the colon is no longer able to contract to eliminate stool, and therefore the cat loses the ability to defecate. It can be part of Manx Syndrome.
• Intertrigo: infection in the folds of the skin
• Corneal dystrophy: malformation of  the eye

Manx may also develop the same illnesses found in other non pedigree cats. Also, they can be particularly prone to periodontal disease (gingivitis and tartar). Dental care is highly recommended.

The Manx gene (M), is a dominant gene, and thus expresses itself as soon as it is present. However, all tailless cats have only one mutated gene, with their other allele coding for a full length tail (m). Thus they are [Mm]. When the mutated gene is completely absent [mm], their tail is simply normal. On the other hand, an [MM] kitten will have so many changes to their spine and spinal cord that they will not survive. The gene is therefore lethal, which makes raising the breed rather difficult.
When breeding Manx cats, it is important to never to couple two completely tailless cats, because the risk of having kittens with Manx Syndrome is very high (30% risk). In general, we prefer to couple a Rumpy with a Stumpy or a Longy.
