Hi Wittesea. I don't have a Maine Coon, just a lovable cat with tons of toes, 26.

He doesn't have double claws, but has a few deformed kind of claws that are really thick and cause him problems, discomfort I think too.

I think it would be a good idea to find a cat site as suggested and see what those folks might have to say.

That is very strange looking!!!! I bet your Maine is beautiful.
