Wolf Rat

The Wolf Rat is a hypothetical path rats could take in a post-human world.

Evolution
After the extinction of humans, rats began to run out of food. Slowly, they began to go back to their habits before humans had came into existence; foraging through various habitats. Over time, rats took up the niche left by wolves (extinct due to humans). They evolved larger, and sharper front teeth, similar to that of beavers, but used for a purpose similar to that of Thylacoleo (the marsupial lion).

Description
Wolf Rats are about the size of a timber wolf (evolving in the wake of these animals). They have adapted to have serrated front teeth, similar to that of beavers, but for biting down on the vulnerable throats of their prey.

Habitat
Forests and Taigas, and other similar habitats where their woodland creature prey lurks.
