Ferret

The ferret was a common animal in the Realms.

Description
Like weasels, these animals were small and furry creatures.

Behavior
Ferrets could be extremely aggressive, but chose to attack smaller prey.

Semberholme
The Semberholme ferret was found in the Semberholme area of the Cormanthor forest. It was characterized by its color-changing fur, which was normally brown, but became white in the winter to provide extra camouflage against wolves.

Swamp
The swamp ferret was found in the swamps of High Moor. Their bodies typically grew to a length of and had deep brown fur with gray or green markings. They were excellent swimmers, as well as a rather cunning and quite vicious species, even by ferret standards. They were unafraid to attack even mammals that were larger than themselves &mdash; Elminster had once heard of a small group of swamp ferrets taking down a full grown goblin. However, they were primarily known to eat young rabbits and rats. They made their nests inside of small trees, usually close to other nests.

Ecology
These animals could be trained and domesticated.
