Full Answer

The number of pups in a rat's litter increases the more litters she has, and then it decreases again when her fertility wanes. The maximum amount of pups a rat can have in a litter is in the mid twenties, but 6 to 12 is more normal. The pups are blind, deaf and hairless at birth, and they rely on their mother's milk for nourishment. They are usually weaned by the time they are 21 days old.

  • Q:

    How have rats adapted to their environment?

    A:

    Rats live in very diverse environments, and they adapt to this wide range through fast breeding, small size and a diverse diet. Rats are opportunistic feeders, taking advantage of whatever food sources are present, relying on stealth, and, as a species, a high replacement rate that protects against predation. Their large incisors, typical of rodents, allow for efficient access to shelter and food sources.
