Guinea pigs should not be forced to share a space with each other unless they are extremely close in their bond. It is preferable if the two guinea pigs are on friendly terms with one another. Once they have formed a bond with their partner, they become extremely attached to them.

Maintain two separate cages for the guinea pigs to allow them to develop a bond with one another. They will gradually become accustomed to one another. They will be able to distinguish between each other based on the smell.

Following their neutering, you can relocate both guinea pigs to a new location that is neutral to both of them. It will be a new environment for both of them, as neither has ever visited this location before.

Both guinea pigs may act as if they are strangers to one another and ignore one another. Ignoring each other is preferable to having a fight between the two of them.

After a period of time, observe their activities and return them to their place of origin. You should keep repeating this activity until they begin to interact with one another in a friendly manner. Keep an eye out for the following signs of a growing bond between them:

  1. Cuddle together
  2. They start playing along and sharing toys
  3. Grooming

Once the guinea pigs have formed a bond, do not separate them until they begin to fight with one another. If you see them fighting, you must separate them so that they do not injure each other further.

Spaying/neutering your guinea pigs

Guinea pigs reach sexual maturity at a young age of 3-5 months, depending on the species. In addition, hormone fluctuations and mood swings occur as a result. Among other things, they are concerned with their own personality. As a result, spaying them becomes essential in order to control their behavioral variations.

During this time, female guinea pigs become more aggressive and territorial in their behavior. They are more sensitive to changes in hormone levels. It is their policy not to allow any unwelcome intrusion into their personal space.

After mating has taken place, you may notice some changes in the behavior of the male and female Guinea pigs toward one another.

Even after the mating has been completed, the female guinea pig will remain aggressive toward the male guinea pig. It is not acceptable for the female guinea to be disturbed while the babies are being breastfed.

Even if a male has been neutered, he will exhibit signs of hormonal change. When they are frustrated, they will attempt to hump over anything in order to find relief.

Although the guinea pig is incapable of reproducing, the hormones it produces will cause it to do so. Guinea pig mounting on others can also be interpreted as an act of dominance.

Neutered males engage in similar behaviors, albeit to a lesser extent than unneutered males.

Guinea pigs of the same gender will fight ferociously if they are kept together in the same enclosure without being neutered. Even if you do not spay your guinea pigs, you can keep two of the same gender together as long as there is no competition between the two of them.

It is recommended to keep guinea pigs in pairs of the opposite sexe to ensure a healthy environment. Even if they are of the opposite sexe, they should be spayed or neutered. An unspayed female may become aggressive toward a male who attempts to mount on her, if the male is not spayed as well.

When kept in mixed pairs, male guinea pigs attempt to assert dominance at first and will even deny female guinea pigs access to the resources they require. However, when kept in a mixed pairing, female guinea pigs eventually learn to exert control over the situation.

To begin with, a spayed female guinea pig will tolerate male guinea pigs climbing up and on top of her. Slowly but steadily, the male guinea pig will be returned to his rightful place. From this point on, they begin to form bonds with one another and eventually become friends.

Provide a large enough cage

Additionally, physical activity is necessary to keep guinea pigs engaged in some activity and in good health. It is necessary to engage in physical activity for at least 5-6 hours per day. Otherwise, because of their inquisitiveness, it is difficult to keep them contained.

Even better is the idea of hiding the food around the perimeter of the cage. Because feed should account for the majority of the food consumed by guinea pigs, this will be beneficial in both directions. They will be given extra food items in the hay as a reward for their efforts.

The chasing will be done with a certain amount of aggression and with the intent to harm others.
