Abyssinian vs Manx

Abyssinians are one of the most perpetually active cat breeds that exists and generally dislike being held or restrained, which is the opposite of what most people picture when a breeder describes a 'friendly, people-oriented' cat.

The same gene that gives Manx cats no tail also frequently disrupts how the spinal cord forms — one cited study found spina bifida in 16% of Manx kittens — and cats that inherit two copies of the tailless gene die before birth, so every living Manx carries just one copy of a gene that, in its more severely affected individuals, causes lifelong hind-leg weakness and bowel or bladder incontinence.
