Guinea pigs make great pets, whatever the gender. The secret lies in getting the right combination.
If you already have guinea pigs, newcomers should be of the same sex, or neutered, to prevent unwanted litters. It’s best to keep guinea pigs in same-gender combinations, so that you won’t have to neuter them. Any operation is stressful and risky for a guinea pig.
Keeping same-gender groups of Guinea Pig prevents you being overrun with baby GPs!
Introducing New Guinea Pigs
When homing more guinea pigs, avoid introducing sows to unneutered boars if the females are over one year old and haven’t had babies before. It is very risky for these sows to get pregnant, as their hip bones will have hardened by this age, and that makes it difficult for them to deliver pups, and can prove fatal.
So, always ensure you’re 100% certain of the gender of all the guinea pigs involved.
Male or female? Make sure you know the genders of all your guinea pigs
An all-female group of guinea pigs is a popular choice. You’ll get very little trouble or conflict in such a troupe. All-male groups are a popular choice too, and after a bit of jostling to establish the hierarchy, they’ll get on just fine. If they’re from the same litter, that’s ideal, as they will have sorted out pecking order already.
