Grizzly bear in Jasper National Park, western Alberta, Canada.
The primary difference between bear and cat claws lies in their ability to retract. Bears possess large, nonretractile claws that remain extended at all times, which are often adapted for digging out roots or small rodents. In contrast, most members of the cat family have retractile claws that can be pulled into a sheath when not in use, with the exception of the cheetah.123
Additionally, the function and maintenance of these claws differ significantly:
- Bears: Their claws are generally better developed on the front feet than the rear, serving as specialized tools for digging and foraging.1
- Cats: Cats use their sharp, retractile claws for hunting and self-defense. They often engage in "clawing" behaviors to shed the outer sheath of their claws, which helps maintain a sharp, healthy layer underneath. When a cat unsheathes its claws, it also spreads its toes, effectively broadening the foot to create a more formidable weapon.43
