Avoid the DAZ rat. It is one of their earliest characters and is not very posable, not very morphable, not very flexible... and doesn't even have decent textures available to cover the plastic. (I wouldn't give it to my cat.) The House Mouse is too cartoony for my tastes but does have a lot of expression and personality. Since he stands upright already, he would be a good start for a ratman. I think the handsomest rat is a labrat at 3dup.com. About 100K polys, and 3ds format only IIRC. I've downloaded JTrout's mouse and chipmunk but haven't tried them out yet. Carolly
