Stoat

Stoats were a species of mustelid or "weasel", a family of small mammals that included ferrets and weasels.

Description
Like weasels, these animals were small and slender-bodied furry creatures, measuring in length from head to tail.

Ecology
Much like ferrets, the fur pelt of a stoat was not considered to be very valuable.

Habitats
In northwest Faerûn, silvered fur stoats could be found in Hartsvale. Beyond Faerûn, stoats inhabited the sub-arctic forests of Kara-Tur.

Relationships
Some wizards were known to have stoats as familiars.
