The highly textured tonguelike base is made of an epoxy composite over steel, painted with pink enamel. The top image above shows how it rests on the base at three places.
The underlying plywood form, naked of fur, is very geometric as you can see here, but you don't see that in the final piece; you can only feel it. I'd like to thank my mom, who found just the right fur for the job. (She says a kitten would like to curl up inside it, so I should have called it Cat House.)
