My cat Eris, a Maine Coon (which means she has a crazy-long, poofy tail) will actually use her own tail as a toy. She also uses it as a pillow and, when she's sleeping in a bright room, a sleeping mask to block out the light.

She also uses her paws like hands, picking up pieces of food from her foodbowl and eating it that way and scooping up water from her water dish and licking it off of her paws.
