The domestic cat is the smallest mammal in the family Felidae. Cats are active agile hunters with fast reflexes and particularly keen eyesight. They have strong, flexible bodies, sharp teeth and retractable claws. Recent archaeological findings suggest that cat-human cohabitation started almost 10,000 years ago in the Near East. The cats is widely used as a model organism for biomedical research, especially in the fields of neuroscience, endocrinology, behavioral biology and reproductive physiology.

The cat genome has 19 chromosomes containing 2.7 Gb with 20,000 protein-coding genes. The reference proteome is derived from the genome sequence published in 2007.
