Dwarf cat

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. Unlike undersized cats of normal proportions, dwarf cats suffer from the genetic mutations osteochondrodysplasia and achondroplasia (a form of osteochondrodysplasia). These genetic disorders of bone and cartilage are typically manifested as abnormal bone shape, poor growth or lack of growth, bowing of the limbs to the side – front legs are more likely to be affected, and spinal malformations.

The breeding of dwarf cats is prohibited in several countries and states, due to the animal’s welfare concerns. Furthermore, except for TICA, all major cat registries do not recognize nor allow the crossbreeding with dwarf cats.
