Mice communicate mainly by vocalizing and by emitting scents (pheromones). PheromonesPheromones Scented substances that have a signaling function for the animal species that secretes them. are produced and excreted by the preputial glands, but are also found in tears and urine.
Of all the senses, the sense of smell is the most developed. Pheromones contribute to communication, they function as an alarm signal for predatorsPredator Living at the expense of other animals by killing them. A predator is an animal that feeds itself by killing and eating other animals. and they play a role in sexual maturation. In mice, pheromones are perceived by an olfactory sense organ called Jacobson’s organ, which is located in the base of the nasal cavity.

UltrasoundUltrasound Sound with a wavelength outside the audible range of the human ear. A ~20 kHz frequency is associated with possible discomfort, a 50 kHz frequency is considered environmentally acceptable. Ultrasound is associated with a state of animal welfare in that animals may emit more when they are stressed. communication

Mice are able to hear sounds outside the frequency range audible to humans (ultrasound). For communication, mice produce sounds that humans can hear, as well as inaudible ultrasound (see movie).

Whiskers

Mice use their whiskers for perceiving objects and the movement of air. Bending of whiskers leads to stimulation of the nerves attached to the hair follicles and these nerve impulses are transmitted to the cerebral cortex.

Nocturnal

Mice are nocturnal animals; they have next to no color perception and they are sensitive to high intensity light. This is especially true for albino animals, which suffer retinal degradation if exposed to light with an intensity exceeding 60 Lux.
