The x-ray on the left is of a declawed cat's paw. The one on the right is a of a cat with intact claws.
A declaw is an amputation, and not always a complete one. Bones grow back. It's like walking with pebbles in your shoe - for life.
Please don't think declawing fixes behavioral issues; it creates them. A lot of declawed cats are surrendered at pounds and shelters due to litter box problems (the cat is upset, in pain, or can't stand the feel of litter on its paws) or biting. A cat without claws has only one way to protect itself.
