Guinea pigs will groom each other, and this reduces stress levels. Grooming is a natural part of their behavior.

Can You Keep Two Male Guinea Pigs Together?

Although guinea pigs are typically kept in same-sex pairs, it is possible to keep two male guinea pigs together.

Stranger males take time to accustom themselves to each other, but if the two males are related, i.e, a father and a son, they will get along better.

If the two piggies are from different families, you can have them in separate cages and then bring the cages close to each other. This way, they can get used to each other’s smell and presence without necessarily fighting.

Can Two Female Guinea Pigs Live In The Same Cage?

Yes, it is possible to keep two female guinea pigs together. Unlike males who fight over dominance, two females will get along better.

A mother-daughter pair is the best, but it’s also possible to house two unrelated females together.

Is It OK To Keep Just One Guinea Pig?

It is not okay to have one guinea pig unless it is a temporary situation or you plan to get another guinea pig soon.

Guinea pigs are social creatures that will feel lonely and bored if they are left alone.

Several scientific studies point to guinea pigs being happier if paired. In fact, paired guinea pigs produced more oxytocin (the hormone responsible for a good mood and general happiness) than a single guinea pig.

There are exceptions where you can have a single guinea pig. These include:

  • A human-oriented guinea pig would rather be around humans than other guinea pigs.
  • A senior guinea pig who has been alone for a long time and is used to it. Such a guinea pig will manifest aggression towards other piggies despite multiple bonding attempts.
  • A sick piggy who is recovering from an illness or injury. In this case, it is essential to have a veterinarian examine the guinea pig and give your permission to introduce another one.

Final Thoughts

It is in the guinea pig’s nature to live in pairs. This way, they are happier and healthier! If you have a single guinea pig, try to introduce a new friend as soon as possible. Make sure you have the right pair though. Guinea pigs should be from the same family. If you need to keep a male and a female, have the male neutered to prevent breeding.
