- desc = "A massive rat, some sort of mutated descendant of normal Earth rats. These ones seem particularly hungry, \
- and are able to pounce and stun their targets - presumably to eat them. Their bodies are long and greyfurred, \
- with a pink nose and large teeth, just like their regular-sized counterparts."

\
+ Rats are various medium-sized, long-tailed rodents. Species of rats are found throughout the order Rodentia, \
+ but stereotypical rats are found in the genus Rattus. This specific species of rat is a mutated decendant from lab rats.\
+ It is unclear what experiment caused this species to grow to such an unnatural size, however it hasn't effected the rat's \
+ general docile nature. When encounterd by human's or other species it generally ignores them unless provoked.\
+
\
+ Rats become sexually mature at age 6 weeks, but reach social maturity at about 5 to 6 months of age. \
+ The average lifespan of rats varies by species, but many only live about a year due to predation.\
+ However, due to the large nature of this particular species of rat, predation is usually not that much of an issue. \
+ This doesn't mean that there is an overpopulation, though, quite the opposite. Giant Rats are rare and this is usually \
+ due to small litter sizes and lack of proper food sources. Areas that one would typically see a Giant Rat is large garbage \
+ disposals or areas that have large amounts of live food (other rats, mice, etc.) such as maint tunnels. \
+
\
+ Male rats are called bucks; unmated females, does, pregnant or parent females, dams; and infants, kittens or pups. \
+ A group of rats is referred to as a mischief."
