Hearing is another important adaptation for hunting. Cats have twenty muscles to move their ears. Being able to move their ears in nearly a half circle helps them find prey quickly. Lynx hear higher pitched sounds than people. They are able to hear a mouse squeaking or a rabbit moving its foot.
Lynx also use their ears to indicate mood.
They lay their ears back when they are angry or feel threatened. These hooks help comb the cat's fur or trap liquid like small cups when they drink. They also help scrape meat off the bones of prey. This meat scraping tool is especially important in winter, when lynx feed on carcasses of larger animals, such as deer and elk, that have died. Cats' whiskers are not just hairs.
