Do cats have chins?
Cats do not have chins, even our closest cousins, chimpanzees and gorillas don’t have chins, in fact, humans are the only animals with chins. However, the area below the lower lip is commonly referred to as the chin, even though it’s not technically correct.
What is a chin?
The chin is a forward-pointing protrusion of the anterior (front) mandible below the lower lip which juts out beyond the teeth. The jury is still out as to the exact purpose of the human chin, but it is thought to be a byproduct of a shrinking face. As humans evolved and became more social and cooperative, aggression reduced along with testosterone levels.
If cats don’t have chins, what is the area below the lower lip called?
The area below the lower lip is referred to as the mandible. Somehow it doesn’t have the same ring to it as chin.

Did you know?
The chin, or mandible (if we’re being anatomically correct) is prone to feline acne. Pet owners may notice what appears to be black dirt in the area due to the presence of comedones (blackheads). Feline acne is associated with plastic food bowls, improper grooming, stress, allergies and excessive chin (mandible) rubbing. Accompanying signs include redness, swelling and in severe cases, pustules.
