The term FELINE WEAPONS refers to the CLAWS of cats, which are their primary defense mechanism. CLAWS are sharp, curved nails that cats use to catch and hold onto prey, defend themselves, and climb. They are made of keratin, the same material that makes up human fingernails. Cats have retractable CLAWS, which means they can extend and retract them at will. This allows cats to keep their CLAWS sharp and ready for use when needed.
