Declaw refers to the surgical removal of an animal's claws, usually performed on cats. The procedure involves amputating the last joint of each toe, which includes the claw, and is typically done for cosmetic or behavioral reasons rather than medical necessity. Declawing can be painful for the cat and may affect their ability to climb, jump, or defend themselves effectively. It's considered a controversial practice by many animal welfare organizations due to its potential negative impact on the cat's physical and emotional well-being.
