Dwarfism is a condition of people and animals marked by unusually small size or short stature. [1] In humans, it is sometimes defined as an adult height of less than 147 centimetres (4 ft 10 in), regardless of sex; the average adult height among people with dwarfism is 120 centimetres (4 ft).
Achondroplasia is a genetic disorder with an autosomal dominant pattern of inheritance whose primary feature is dwarfism. [3] It is the most common cause of dwarfism [4] and affects about 1 in 27,500 people. [3] In those with the condition, the arms and legs are short, while the torso is typically of normal length. [3]
A dwarf cat (sometimes nicknamed a sausage cat [1]) is a domestic cat with dwarfism due to rare genetic mutations that cause a disproportionate feline body. The mutation usually leads to significant health problems.
Dwarfism in Cats In cats, dwarfism has similar causes as what produces the conditions in human beings, being caused both by genetic disorders and by pituitary malfunctions.

Dwarfing is a process in which a breed of animals or cultivar of plants is changed to become significantly smaller than standard members of their species. The effect can be induced through human intervention or non-human processes, and can include genetic, nutritional or hormonal means.
Culling is not strictly necessary if genetics are the only issue in hand. Small animals such as cats and dogs may be sterilized, but in the case of large agricultural animals, such as cattle, culling is usually the only economic option. The issue of casual breeders who inbreed irresponsibly is discussed in the following quotation on cattle:
The disorder leaves the cat with a full-size body, but disproportionately short and thick legs. Dwarf cats often suffer from spinal disorders, such as lordosis (excessive curvature of the spine) and pectus excavatum (hollowed chest). [7] As with human dwarfism, there are still a lot of unknown mysteries in the science behind feline dwarfism.
