Members of the cat family – including domestic cats and wild cats like the lion – have dewclaws. Generally a dewclaw grows on the inside of each front leg but not on either hind leg. The dewclaw on some cats is not vestigial. Wild felids use the dewclaw in hunting, where it provides an additional claw with which to catch and hold prey. The dewclaw may not be used by domestic cats, however, and pet owners should trim their cat's dewclaws regularly so they do not curve into the vestigal pad.
