Cats Cats also called the domestic cat or house cat (with its scientific name: Felis Silvestris Catus or Felis Catus) is a type of carnivorous mammal of the family Felidae. The word "cat" generally refers to a "cat" that has been tamed, but can also refer to the "big cats" such as lions and tigers. Cats are considered as "perfect carnivore" with teeth and particular digestive tract. The first premolar and molar teeth form a pair of fangs on each side of the mouth that works effectively as a pair of scissors to tear the meat. Although these features also exist in the Canidae or dog, but these traits are better developed in cats. Unlike other carnivores, cats eat almost non vegetable substance. Bears and dogs sometimes eat berries, roots, or honey as a supplement, while cats only eat meat, usually freshly killed prey. In captivity, cats can not adapt to a vegetarian diet because they can not synthesize all the amino acids they need from plant ma.
