How Much Should A Guinea Pig Weigh?

Guinea pigs are lovely creatures and provide us with bundles of joy and unconditional love. These warm and beautiful creatures should be taken care of in the appropriate manner. Weight is a critical factor for any guinea pig.

It is often noticed that a healthy and happy guinea pig maintains his/her health. So, a guinea pig owner must carefully monitor the health of these creatures to ensure they are comfortable and not suffering from any type of illness.

Also, taking their weight regularly is very important. When the guinea pig falls ill the information regarding weight will help the vet.

Although the weight can vary between individual guinea pigs, there is usually a range to determine if the guinea pigs are growing in a healthy and proper way. The owners must be alert about their weight and should take necessary precautions to ensure that their weight is well maintained.

Why Is A Guinea Pig’s Weight Important? 

Guinea pigs are very beautiful and cute creatures. Like all other pets, they can also get sick and often this sickness can be diagnosed by weighing them.

An owner should check the weight of the guinea pigs weekly if not daily for significant changes.

If they are losing their weight within a short period, it more often than not means that they are sick. Thus, the owner can take the necessary measures to take the guinea pig to a doctor.

Ideal Weight For A Newborn Guinea Pig

Newborn guinea pigs can weigh from 40-120 grams. This wide range is given considering the different types of guinea pigs. Weight of a young guinea pig should be in this range, but even if it is not, the owner must not worry because, in this early stage of its life, it isn’t a cause for alarm.

The range is so broad because many variations of guinea pigs exist. An owner must not be too worried about the weight of a newborn one.

But an owner should always be careful in case there is a vast and noticeable difference. If any guinea pig gives birth to 3 guinea pigs and 2 of them weighs 30 or 40 grams more than the other one, then the owner must provide extra care to the one who weighs the least.

Average Weight Of Matured Guinea Pigs

Guinea pigs can grow fast, and a male guinea pig will grow more quickly than a female. After it is born, the cavy usually gains 30-50 grams every week if it is happy and healthy in its environment. A healthy and happy guinea pig usually maintains its weight naturally.

These lovely creatures usually grow fast, and the increasing weight begins to decline when they are 12-14 months old usually. By this time, a matured male guinea pig may weigh from 900-1300 grams while a female guinea pig will weigh around 700-900 grams.

Guinea pigs are also like human beings, and all of them have different bone structures, and thus an owner should not be worried if the guinea pig weighs a little bit more or less than the average.

But an owner must be careful if he/she notices any problem with their guinea pigs. Also, they may also check for the heft around the ribcage which is a good way of knowing if the weight of the guinea pig is at normal levels.

As the guinea pigs get matured, they lose their weight and starts to become skinnier. When a guinea pig is 4 years old or higher, they will most certainly lose a lot of mass.

The average weight should be brought into consideration by the owners for a matured guinea pig only, and the owner must not be worried if the weight of the guinea pig is slightly above or below the average range.

Increase In Weight During Pregnancy 

A female guinea pig or mostly known as a sow will go through various changes when she is pregnant. Usually, a sow remains pregnant for 9-10 months, but the weight of the sow mostly increases during the last 50-60 days of pregnancy.

When a sow is pregnant, it shows many signs. But the extra weight is only seen during the last period when the sow can weigh twice as much as its original weight.

There is not much to be concerned about with the sow's extra weight, but if the owner notices anything abnormal, then they must go to the vet at once because there may be a problem regarding the pregnancy. A pregnant sow requires a lot of extra attention.

Overweight And Underweight Guinea Pigs 

While checking for the heft, if you can feel the ribcage is protruding outwards, then you may conclude that the guinea pig is underweight and if it can't be felt at all, then it may be overweight.

Usually, these animals have a high metabolism, and thus they are decidedly less likely to get overweight. But if a guinea pig is underweight, the owner will have to take extra care.

When a guinea pig loses more than 100 grams a day, it may be understood that it is ill and should be taken to the vet immediately. Also, if a guinea pig loses 50-100 grams of weight per day, it must also be monitored closely. That is why a daily weight check is essential.

Final Thoughts

Pets are no different than humans and can't be put under a single label. There can't be any specific weight fixed for all guinea pigs as there are a lot of different breeds.

The ideal weight should be kept in mind by the owners but, it should not be the only signal to come to any conclusion about the sickness of the guinea pig.

Their weight must be checked weekly and monitored closely for any type of anomaly, and also in case of a drastic change, the guinea pigs must be taken to the vets.
