How do you tell a boy guinea pig from a girl?

How can you tell if your guinea pig is a girl or a boy?

• Answer:

  Well you have to look at their bottom. For a boy they will have a boy part sticking out and for a girl they will have nothing You can tell if you take them to the vets. the vet can tell because he will feel for testes which only the males will have. Girls are normally a little more shy than boys personality wise Gently turn your guinea pig onto it's back in your hand. Gently but firmly press two fingers, one on each side, around the area slightly above the pig's rectum, where you would normally expect genitalia to be. You will see a little hole. This is where you want to press around. Where you would expect to see a penis, if it's a male, it will appear. If not, it is a female. Check its genitalia. A penis would indicate you have a male, a vagina would mean female. Anything else and you've got a problem. Male guinea pigs will have testicles (as long as they have not been neutered). They are small but noticeable.
