Not something you've ever thought about?

Many animals have different skin colours to the fur colours. Some cats have black pads on thier paws when they have white fur. Many dogs and cats have various skin pigments. Polar bears have black skin under thier white fur. This is thought to help them attract heat in he arctic conditions. Chows have black tongues!
So the answer to the skunk.....very pink skin.
Steve has now had a cruciate operation to fix his knee as that joint had become unstable. She is now receiving physiotherapy to help her recovery. So far she is doing really well. Keep up the good work Steve!
