Query: Please don't use these

I have used soft claws in the past, with success. Recently, I decided to use them again. However, this time, one of the soft claws never fell off. I kept waiting for it to fall off, or for my cat's claw to grow long enough that I could clip it off....It never happened.I am taking my cat to the vet tomorrow to get the soft claw removed. The claw is pressed against his paw pad, so I have no other choice. I can't clip it off, because the nail is too thick. IT WON'T COME OFF.They just aren't worth it.
