The domestic cat is a member of the Felidae, a household that had a common ancestor about 10–15 million years ago.The genus Felis diverged from different Felidae around 6–7 million years in the past. Results of phylogenetic analysis confirm that the wild Felis species developed via sympatric or parapatric speciation, whereas the home cat advanced through artificial choice. The domesticated cat and its closest wild ancestor are diploid and each possess 38 chromosomes and roughly 20,000 genes. The leopard cat was tamed independently in China round 5500 BC.
Adult females require around 200 to 300 energy per day, whereas grownup males want between 250 and 300 calories per day. In order to kill their prey, all felids bite the again of the neck at the base of the cranium, thus, severing the spinal chord from the mind stem. Primary prey for feral animals contains small rodents, birds, fish, and some arthropods. Occasionally, domestic Cats ingest plant materials to meet fiber deficiencies.
