Guinea pigs are absolutely not aggressive and not dangerous to humans.

Keeping a larger number of these small, cute rodents provides an opportunity to get acquainted with their behavior in the herd, allows you to observe the various morals that can manifest themselves only when the pig feels safe surrounded by its relatives.

The pig does not bite or fight the enemy. To unfamiliar surroundings, smells, sounds – everything that seems unsafe to her – she reacts with a panicky flight or absolute immobility. Under natural conditions, this behavior often saves the lives of these rodents. 

These meek animals show aggression exclusively against individuals of their own species. It can be found between gilts competing for food or resting places. Mothers, after the end of the lactation period, sometimes drive away their cubs, the same get angry when milk becomes insufficient.

Often the cause of aggression is the excessive concentration of animals forced to stay together in a small space. Examples of aggressive behavior include mutual plucking of fur and eating what is left in the mouth. Displeasure also manifests itself in the form of a sharp turn and a jump directed towards the enemy. When the pig turns around, it crouches, opens its mouth, often snapping its teeth warningly and bristling its scruff. 

The most formidable conflicts come between two males fighting to conquer dominance over the herd. Two males, chattering, snapping their teeth, raising their hind legs alternately, circle one around the other. If neither of them gives up on this introductory game, they start bouncing at each other and biting. Refusal to fight even at the stage of the “war of nerves” does not always save the surrendered person from being bitten. For the victor can pursue the defeated one and gnaw at the places he can reach with his teeth.

Under natural conditions, bloody conflicts happen very rarely because the weaker male has where to run and where to hide. When breeding in confined spaces, this kind of incident can be unsafe. 

Females, as a rule, tolerate each other well, but even here there is a certain hierarchy: the leader puts things in order among her same-sex relatives and babies. All females take care of the health and development of the offspring. In the first week of life, babies are fully supported by the female. If one cub wants to eat, he can get milk not only from his mother, but also from another lactating female. If the baby is alone, he begins to emit a loud, plaintive squeak until the mother hears him: she comes up to him, making rumbling sounds, sniffs, licks his face, and then puts him in place. From the second week, babies become more and more attached to the male, who weaned them from maternal care, starting from the third week, the mother stops feeding them with milk.

There is no escape route in a guinea pig cage or aviary, so you are responsible for the peaceful coexistence of the animals. Please note the following.

For young males, upon reaching puberty, that is, no later than 4-5 weeks, other hosts should be found. This is necessary not only to avoid hassles, but also to prevent uncontrolled further reproduction.

If the male is defeated in the struggle for the dominant place in the family, he must be immediately placed in another enclosure, otherwise he will wither away, since there is no longer a place for him in the family.

A young castrated male who has been placed in a group of females will probably not be able to immediately establish himself as a host. The situation will change only over time, when he grows up and will surpass females in size and weight.

The guinea pig, which shuns its relatives, probably did not have contact with other guinea pigs from an early age, due to which it lacks a sense of community with the group and therefore it is very difficult for it to get along with its fellows.

If you want to place a group of guinea pigs in a new cage with other guinea pigs, then you can safely do it. A separately kept guinea pig is more difficult to add to several animals, among which it will have to get along. In addition, several animals require a larger cage.

The female dissatisfied with courtship often defends herself from the annoying male. Her defensive reaction consists in the fact that she, having doused the impudent person with a stream of urine, starts to run. She succeeds because the male pauses for a moment to sniff himself. Several energetic jumps of an angry female can also discourage a male from flirting. 

The sign of reconciliation is the opening of the most delicate parts of the body by the mumps, those parts that are easiest to injure. Many other species of animals behave in a similar way. The pig stands on fully straightened paws and throws its head up, revealing its muzzle and neck. Such postures are adopted by individuals subject to the influence of their stronger companions, and males in relation to their partners. 

Hearing in guinea pigs is simply wonderful, it is he who is of paramount importance in the perception of the environment.

Vision in guinea pigs is also very well developed. As a result of the experiments, it was found that guinea pigs distinguish colors, primarily yellow, red, green and blue.

Guinea pigs have a perfect sense of smell. They are well oriented by smell. When greeting, they sniff each other, paying particular attention to the anus and ears. They mark their territory with odorous substances, urine and secretions of the glands. You should not be surprised when a pig, admitted to its tidied home, walking through it, will rub its backside on the bedding. This is a way to mark the area with the secretion of the glands located near the anus. Males also use glands located on the sides of the body. With a secret that stands out from them, they mark the members of the herd and objects located above the floor (flooring).

The organs of touch in guinea pigs are located in the antennae that grow around the muzzle. They help the animals navigate in the dark and avoid obstacles.
