With their claws retracted, lynx paws make no noise. This helps them sneak up on their prey. Listen to a dog walking down a sidewalk or across a hard floor. You can hear the dog's claws click, click clicking as it walks. Compare that to a cat walking down a sidewalk . . .
Lynx have short jaws.
Their short jaws give them a wide, strong bite, making them capable of killing their prey in a single bite. Shorter jaws have fewer teeth. Lynx have only 28 teeth. Mountain lions have 30. Black bears and coyotes have 42.
