Double claw kitties

I was reading up.on ” double clawed” kitties & found that there aren't many people who know what it is... I of course assume it's a genetic defect but have only seen it once and was curious as to how rare it is. I have an excellent picture of the kitties toes if anyone is interested in seeing it. (This is, the cat has an ” extra set” of claws growing out of his paw pads on each and every toe, in the opposite direction of his regular claws, best described to form ” pincers”... Not to be confused with a polydactyl which simply has extra toes)...

I have heard of something like this happening after an incompetent declaw, and I think someone on here a while back showed us something similar, but, again, I'm not sure it was all of the claws, and it may have been due to an injury.

Have you found any photos?  Or do you have some of your own?  Is this a problem your cat has?

Lets see the picture.  I have polydactyls, but have never heard of what you are describing, and Im curious.  Front feet, and back?
