Size and weight of the guinea pig

Come weight, the males of the guinea pigs can weigh 1,250 grams, with a length of about 20 cm.


The males of the guinea pigs become fertile as early as 2 months of life, while the females at 5-7 weeks. Never mate the female before 3 months and never after 7 months if you have not already given birth before: in this case the bones of the pelvis ossify thus preventing delivery and causing dystocia, with the risk of life for the mother and the little ones.

The duration of pregnancy of the guinea pig is 63 days (59-72). As early as 2-15 days after giving birth, she can return to heat. From each birth, 1-6 babies are born, with an average of 3. The weight of the puppies at birth is 85-95 grams. The young are precocious: they are born already equipped with hair, with open eyes and are able to walk. Within days of birth they begin to taste the solid foods given to the mother, even if they are weaned at 2-4 weeks.

What character do guinea pigs have?

Come character, the guinea pig it is a social animal that lives in small groups with a hierarchical structure. Usually the group is formed by a dominant male with attached harem, all other males banned. In captivity, it is better not to put males and females together to avoid reproductive problems. Technically, a small group of males can coexist peacefully together, as long as there are no females around.

In nature, the guinea pig is active early in the morning and at sunset. In captivity it tends to assume more human circadian rhythms. She is used to having long periods of activity interspersed with short naps.

Guinea pigs are not among the rodents more athletic: they can make very small jumps to overcome obstacles, but they don’t jump as much as other rodents. However, when they are happy, they tend to jump up and down with a movement called “popcorning” because the sound they make during this attitude is reminiscent of the crackling of popcorn. The guinea pig loves digging burrows and hide in them. With his own human, if well socialized, he is attentive and affectionate, greeting him with squeaks and whistles.

Being social animals, guinea pigs should never be kept alone. Never put males and females together if not sterilized and never put males together if there is a female in the house. Males can only coexist with each other if there are no females around. More females, on the other hand, can coexist with each other without any problem.

Guinea pig and management of its accommodation

Although it would be better to keep the guinea pigs free in a room specially dedicated to them (therefore where all dangers have been removed including power wires, gnawing objects, holes to slip into …), if it is not possible to organize a special space for them , it is advisable to have one very, very large cage because they have to do enough physical activity.

Better to opt for plexiglas, plastic or steel cages, which are easier to clean than wooden ones. The bottom they must not have a grid, otherwise the legs will become entangled and are at risk of fractures, but there must be abundant litter that must be changed often.

The litter it must be non-toxic and must not be ingested by the guinea pig. Better to use hay if unsure, never sawdust, straw or cat litter. As drinking troughs, use both the classic drop ones and bowls heavy enough not to be overturned. A small house must not be missing in the accommodation: it will be the guinea pig’s den.

The cage should not be exposed directly to the sun, in the middle of the draft or in noisy areas of the house. In addition, guinea pigs tolerate low temperatures well, but not high ones. Like rabbits, in fact, they could develop heatstroke already at temperatures above 18 degrees, especially in hot and humid environments.

When you decide to free her at home, always make sure that you have removed all possible and imaginable dangers, including potential predators such as dogs and ferrets.
