Oh, rats. One of the better-known but woefully misunderstood creatures to walk this planet, rats are often viewed in a negative light. Contrary to popular opinion, rats are fastidious groomers and highly sociable animals; domestic varieties truly enjoy the company of humans. Altruistic, they share their food with their friends and come to the aid of fellow rats in trouble. In experiments, rats would attempt to free other rats from a cage before obtaining a piece of chocolate for themselves. These traits, as well as their intelligence, make for a wonderful pet with plenty of personality. Rats both in the wild and in captivity also enjoy as much variety in their diets as humans. The pet rat in this video may also be as picky as some.
