Ear muffins?

Now that it's getting cold here in the California, Polecat's ears sometimes get cold. How do you fix this? Warm ear coverings of some sort would help, but what are they called? It could not be 'ear muff'; we all know what that refers to. Warm, maybe. Okay to wear on your ears? Um. No. It must be time to think about going to buy some ear muffins. Warm is right, the general shape is even right. The English language, it seems, is not right.
