Online vet, Dr. Marie

Dr. Marie replied:

Guinea pigs can go into heat every 15-17 days. (For some guinea pigs it is 13-21 days). When a guinea pig is in heat they can show the following signs:

  • Increased activity

  • Chasing cage mates

  • Swaying hips/hind end

  • Making a low pitched sound

  • Arching her back and then putting her bum up in the air

  • Swollen vulva



So, it can be normal to see a swollen vulva on a guinea pig every 2-3 weeks. This swelling should only last 6-12 hours if it is due to a heat.

However, if the vulva is really swollen then there may be something more serious going on. Sometimes a guinea pig can have a swollen vulva, or even a slightly prolapsed vulva (i.e. some of the tissue from inside is sticking out) because of bladder stones, cystic ovaries, a urinary tract infection or a cancer of the reproductive tract.

If you think this is not a normal heat cycle then a vet visit would be the best idea.

Hope all is well!

Dr. Marie.
