Who has vibrissae better developed and why: a dog, a cat or a rat?

Vibrissae are large, sharply protruding above the general fur coat, usually single bristle hairs. They serve for touch, located on different parts of the body, with which the animal comes into contact with surrounding objects (end of the muzzle, belly, limbs). They are better developed in animals, which are more active at twilight and at night. Consequently, vibrissae are better developed in cats and rats than in dogs.
