| A very loooong rat or something like that. |
Rats are various medium sized rodents. "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, R. norvegicus.
Many members of other rodent genera and families
are also called rats and share many characteristics
with true rats. A rat has an average life span of
2-3 years.
Specially bred rats have been kept as pets at least
since the late 19th century. Rats are sociable,
intelligent animals and can be trained to use a
litter box, come when called, and perform a variety
of tricks. Pet rats are typically of variants of
the species R. Norvegicus, or Brown rat, but Black
rats and Giant pouched rats are also known to be
kept. Pet rats behave differently than their wild
relatives depending on how many generations they
have been removed, and when acquired from reliable
sources, they do not pose any more health risk than
other, more common pets... |
