Diversity in Living Organisms

Domesticated cats can be trained to perform many simple tasks.

Directions: Read the passage and answer the following question.

The Cat (Felis silvestris catus), usually called the Domestic Cat or House Cat is a small flesh eating mammal. Cats are normally very active during twilight hours of the day like dogs, deer, mice, red pandas etc. and hence called crepuscular mammals. Domestic cats are considered to be very social and can easily get along with human beings and even with other pets kept by human beings. Another fact that endears cats to human beings is that cats feed on nuisance creating pests like worms, insects and rodents called vermin. Due to these reasons house cats are considered to be good companions to human beings and are greatly valued by them. According to researchers, the human-cat association has been there for more than 10,000 years.
Cats are highly skilled and specialized hunters. It is known that they hunt over 1,000 different species for food. They are also found to possess a higher level of intelligence and have also been known to have learnt to operate simple mechanisms such as doorknobs. Cats use varied vocalizations and typical body language for communication. These vocalizations include mewing (meow or miaow), purring, hissing, growling, squeaking, chirping, clicking, and grunting. Due to their popularity as preferred pets, cats are also bred and shown as registered pedigree pets. This is a hobby known as Cat Fancy.
A study conducted under the aegis of the National Cancer Institute and published in the journal Science says that all house cats are descendents of a group of self-domesticating wild cats called Felis silvestris lybica found in deserts in the middle east area about 10,000 years ago. Another interesting fact about cats in general is that while almost all wildcat subspecies can interbreed, no such cross breeding is seen in domestic cats and they are all genetically contained within the specie.

Cats hunt vermin to be friendly with human beings.
