Do Guinea Pigs Get Pregnant?

Here we can see, “Do Guinea Pigs Get Pregnant?”

Like all other female mammals, female guinea pigs have a uterus that hasn’t been medically altered. Although they share body parts with humans, dogs, and other species that bleed during their estrus cycles, guinea pigs do not bleed during the heat. If a female guinea pig is bleeding, she should see an exotics veterinarian.

So, where did the blood come from?

It’s possible that the bleeding is still coming from your guinea pig’s uterus, but this isn’t usual. She could be suffering from an issue with her ovaries, uterus, or bladder. Infections, tumors, and uroliths (bladder stones) are just a few things that might make you bleed.


Like dogs and cats, Guinea pigs can acquire pyometra (which means “pus in the uterus”), which is caused by a nasty infection. Antibiotics are ineffective against such a severe infection. Thus the only option is for the guinea pig to be spayed.

Uroliths, often known as bladder stones, are also common in cavies.

When minute crystals in the bladder cluster together to form a stone, it is called a bladder stone. Changes in the urine pH cause these crystals to develop, and some study suggests that a high-calcium diet may also be to blame. Surgery is the only way to get rid of too big stones passing through the urethra. By taking radiographs, an exotics veterinarian can rule out bladder stones.

Urinary Tract Infection

Blood can travel through the urine due to a urinary tract infection (UTI) or cystitis (bladder inflammation).

Blood-tinged bedding or drips that emerge while she isn’t trying to urinate may lead pet owners to believe that the bleeding is coming from the uterus, but it could be coming from her urine. If a cavy urinates on a non-porous surface, such as a hard kitchen floor or an empty plastic litter box, try collecting the urine with a syringe or pipette and bringing it to an exotics veterinarian. The guinea pig’s urine will be tested for infection, and the doctor will determine whether the guinea pig has a UTI or cystitis.


A lump or tumor on any section of a guinea pig’s reproductive or urinary tract, whether malignant or not, can cause her to pass blood. The mass could be aggravating the organ to which it is linked, or it could have started bleeding, and the guinea pig is just passing the blood. If this is the case, surgery will be required to determine whether the tumor can be removed.

Surgical Concerns

Whenever surgery is performed, there are dangers involved. Guinea pigs are easily stressed, and because they cannot be intubated during surgery, maintaining an unobstructed airway can be challenging. Keep the hazards in mind and have your favorite cavy operated on by an expert exotics vet. Experts also advise bringing the other guinea pigs to the hospital with the sick guinea pig to help keep her calm.

Preventative Actions

Spay a guinea pig between the ages of 4 and 12 months to reduce the risk of a tumor or infection in her reproductive tract. After her pelvic bones fuse, this will also prevent her from becoming pregnant.

Feed your guinea pig a balanced and appropriate diet of green veggies, timothy hay, or sweetgrass, and a modest quantity of pellets, coupled with proper fluid intake and vitamin C, to help prevent uroliths. In mature cavies, a diet consisting of alfalfa hay and a significant quantity of alfalfa pellets can aid in the formation of uroliths.

User Questions

Should I separate my pregnant guinea pig?

If you find a pregnant sow and a male in the same cage, you must separate them. Further mating efforts by the male could damage the expectant mother, and if he is in the cage when she gives birth, he could impregnate her right away.

Will guinea pigs eat their babies?

The majority of female guinea pigs will never intentionally eat their live offspring. She may, however, consume one or more of her litter if it is stillborn. In guinea pigs, cannibalism is frequently done by the mother to protect the rest of her litter from predators.

Can I touch newborn guinea pigs?

After the birth, they will be tender and protective of their infants. Thus it is better to leave them alone for a month later. For at least one week after birth, baby guinea pigs should not be held at all and must always be handled gently.

Does a guinea pig’s water break?

The guinea pig may be born in an amniotic sac. This is natural, and the new mother will usually make an effort to break it for the baby guinea pig to emerge and take its first breath!

Do girl guinea pigs have periods?

Female guinea pigs have estrous cycles, in which they go into heat for several days at different periods throughout the year. They do not. However, experience bleeding or periods like they would during a menstrual cycle. They are fertile and go through spontaneous ovulation while in heat.
