Testing out mixamo on a character model of mine i call "berry" who was supposed to be a bear, but funny enough she looks more of a cat then she does a bear.
mixamo is a animation library as well as a autorigging system that is rather new and free for thoses who have the photoshop bundle pack.
as much as i enjoy the website and the autorigging, there are some flaws, especially if your making multi limb characters as well as those with tails or wings, but they do get you started on a base model you can edit in blender to meet your standards and give you a quick start up base.
Berry the cat bear!
