Before you get a baby guinea pig from your local pet store or breed your guinea pig, you need to know how to care for them properly.

Baby guinea pigs are precious little guinea pigs born and birthed into the litter. They usually have ears and legs bigger than their body and require utmost care when handling them.

In this article, we will help describe everything you need to know about baby guinea pigs, from fun facts about baby guinea pigs to the best way that you can care for them.

Newborn Baby Guinea Pigs: Fun Facts

Baby guinea pigs are born precocial. This means that you will find them covered in fur, and they already have teeth as well. They will also be able to move around, see, and hear after some moments.

Furthermore, guinea pig babies are born and birthed into a litter. Female guinea pigs are known to nurse their babies, will breastfeed, and teach them how to groom themselves.

This is why it is recommended not to separate baby guinea pigs from their mothers for at least a month.

Can You Touch a Newborn Guinea Pig?

Yes, you can handle a new guinea pig baby even during their first week as long as you don’t interfere with the birthing process. However, you will need to handle them with utmost care because they are very tiny.

You need to avoid handling them for too long as this can affect their bond with their mother. It is best to allow baby guinea pigs to spend time with their mother to nurse and give them warmth.

Another thing is that a mother guinea pig can reject a baby guinea pig if you don’t allow the baby to bond with her.

What Does a Baby Guinea Pig Look Like?

The average size of a guinea pig baby is about 3-5 inches at birth and weighs around 60-115g.

Generally, the size of a guinea pig baby is directly related to the litter size. If there are more babies in a litter, the smaller each baby will be.

Newborns usually have big paws and heads when compared to their bodies. Furthermore, their body is covered with fur even at birth. Newborn guinea pigs also have tiny mouths with around 20 teeth, growing continuously.

After birth, newborn guinea pigs will start to move once they have been licked clean by their mom.

What Are Baby Guinea Pigs Called

Baby guinea pigs are also known as pups, just like baby dogs are called. However, male guinea pigs will be called boars once they grow up, while the females will be called sows.

Many call guinea pigs juniors once they reach sexual maturity but have not reached their full adult weight.

How Do You Know Gender Baby Guinea Pigs?

It is best that you know how to know gender baby guinea pigs to help ensure they don’t mate with each other. This is because allowing siblings to breed can lead to congenital disorders in their offspring.

It can be quite hard to definite sex baby guinea pigs on your own without knowing. Many owners recommend that you seek the help of a vet or an experienced mentor to sex them.

The best way to define the gender of your guinea pig is by holding them gently on their back. Guinea pigs like being held in this position for long, and you should be prepared to do this very quickly.

The male baby cavy will have a donut-shaped genital opening found in front of their anus. You will feel the shaft of their penis under the skin by carefully running your finger over the area. The penis can also appear if you push the area gently.

On the other hand, female baby guinea pigs have y-shaped genital openings found closer to their anus. Unlike the male, you will not feel a penis when you run a finger over the area.

As stated above, allowing siblings to breed can cause congenital disorders in their offspring. This means you will need to separate female and male baby guinea pigs from each other after their mother fully weans them.

This will help to ensure both siblings do not breed with each other.

How Long Do Baby Guinea Pigs Stay With Their Mothers?

Baby guinea pigs are usually fully weaned at six weeks old and don’t need to be nursed by their mother afterward. They should be ready to leave the nest after six weeks as they have learned to be independent of their mother.

You can separate baby guinea pigs from their mother during this period. This is also the age when most breeders will make a guinea pig available for sale.

How To Care For Baby Guinea Pigs

It is important that you provide adequate care for your baby guinea pigs to ensure they grow well and live healthily. You will need to put them in a roomy cage and ensure the cage is placed in a quiet area. This is because guinea pigs are sensitive to noise.

Furthermore, you need to place their cage away from direct sunlight and from a vent blowing air into the cage. Another thing is that you need to weigh your pup regularly to make sure they are gaining steady weight.

Although mother guinea pigs will nurse their pups, you will also need to provide food for them. You can start offering them shredded lettuce but ensure you remove the leftovers as they can spoil quickly.

After the third day, you can introduce fresh hay, pellets, and green vegetables to them. There should also be a constant supply of fresh water for the pups.

Baby Guinea Pigs and Their Mother

Mother guinea pigs will start to nurse their baby guinea pigs immediately. The pups will even begin to eat solid foods after three days once the mom shows them. They will need to be with their mother for at least three weeks.

During this period, the mother guinea pig will teach and help their pups a lot of things. She will help stimulate the pup to urinate and defecate while periodically cleaning their bottoms.

The mother will also produce softer stool that the babies can consume to have proper bacteria in their digestive systems.

After 3-4 weeks, it is important that you separate the male pups from the sisters and mother. This is to prevent accidental pregnancies as they reach sexual maturity in this period.

You can also separate the female from the mother after four weeks.

However, a female guinea pig baby and its mother can stay together in the same cage. The mother will stop nursing her after four weeks, and she can fend for herself afterward.

Baby guinea pigs will then live an independent life around six weeks old. You can then rehome them after eight weeks as they will be fully weaned and will be eating solid foods.

It is recommended that a vet should examine pups before you send them to a new home.

Baby guinea pigs need food for survival, and you can help a neglected pup through assisted feeding. The first thing to do is to first try out natural feeding before starting syringe or bottle-feeding them.

You can do natural feeding if the mother guinea pig is not too stressed and can tolerate it. Here are the steps that you can follow:

  • Hold the mother guinea pig firmly in your arms and put each baby onto her nipples to suckle.
  • Allow a small amount of milk to come out from the nipple to help entice the baby to suckle.

However, if this does not work, you will need to do assisted feeding.

  • Ensure you wash the syringes and bottles thoroughly before you use them.
  • Ensure you feed the baby guinea pig in a safe environment as they can die if they drop from one or two feet.

  • You can wet the baby’s lips with a drop of the warm formula to entice it.
  • After it licks it, you can then repeat the procedure gently.
  • Don’t force or squeeze too much formula into the pup’s mouth.
  • You don’t need to add any pressure if the baby guinea pig grabs the teat and begins suckling. You may accidentally aspirate your baby guinea pig if you use extra force when a baby guinea pig is already suckling the bottle.

Note: hand-feeding your baby guinea pig can be quite hard if they cannot suckle. You can reduce the risk of aspiration by holding the syringe tip or teat sideways.

Generally, newborn guinea pigs cannot defecate or urinate on their own. Their mother normally uses their tongue in their bellies and genital region to help them urinate and pass out feces. You can help a neglected baby guinea pig by mimicking this behavior.

Use a cotton ball moistened with warm water to rub the pup’s belly and genital area gently. You should continue doing this until their abdominal muscles tense and release urine. This process usually takes 15-20 seconds of stimulation.
