Rats are various medium-sized, long-tailed rodents of the superfamily Muroidea. “True rats” are members of the genus Rattus, the most important of which to humans are the black rat, Rattus rattus, and the brown rat, Rattus norvegicus. Many members of other rodent genera and families are also referred to as rats, and share many characteristics with true rats.I really hated when I see a dirty rat roaming here and there in my house.

Rats very lovable animals. They love being in the group of their own species or humans. They like playing collectively and love to sleep curled up together.

The term rat generally refers to the two main species of house rat, the Norway rat and the Roof rat. Both species originated in Asia, but have spread throughout the world by human travel overseas. They both belong to the genus Rattus, which includes 51 species.
Norway rats have a heavy and thick body about 7 to 10 inches long. They weigh about 10 to 17 ounces. Their color may vary from grayish-brown, a pure gray to a blackish- or reddish-brown. Their underside is gray to yellow-white. Their nose and muzzle are blunt, their eyes are small and their ears are close to the body and won’t cover the eyes if bent forward. Their tail is dark on top with a lighter underside and shorter than their head and body.

Their nose and muzzle are pointed, their eyes are large and prominent and their ears are large and cover the eyes if bent forward. They have a hairless tail which has a uniform color and is longer than their head and body.
