Furrette 2 and Furraldo are very nice anthropomorphic figures, free, and with a useful range of clothing and textures available. They're produced by Little_Dragon and available through
Renderosity and the
www.448studios.com website. There are morphs and textures for various sorts of critter, including foxes and skunks.
You can't really say they're realistic, but on a scale with
Posette at one end and P5's Barney at the other, they're somewhere around Mayadoll
