These cats are also known as Hemmingway cats as alluded by Lise. Some do have problems with getting their claws caught in things and not being able to un-hook. Otherwise it really isn't much of a problem for them.

One of my kitties growing up was named paws because he did have an extra toe. After several rescue from the trees, he learned not to climb trees.

They do have big PAWs.
