Hairless breeds of guinea pigs have been used in scientific research since the 1980s, particularly for dermatological studies. This is in part because research into the genetics of guinea pigs has lagged behind that of other rodents, although geneticists W. E. Castle and Sewall Wright made a number of contributions to this area of study, especially regarding coat color.

[124] Allergy shots can successfully treat an allergy to guinea pigs, although treatment can take up to 18 months. [115] Other genetic disorders include "waltzing disease" (deafness coupled with a tendency to run in circles), palsy, and tremor conditions. [158] Guinea pigs have been launched into orbital space flight several times, first by the USSR on the Sputnik 9 biosatellite of March 9, 1961 – with a successful recovery.

Guinea pigs (called cuy, cuye, or curí) were originally domesticated for their meat in the Andes. [134] It continues to be a major part of the diet in Peru and Bolivia, particularly in the Andes Mountains highlands; it is also eaten in some areas of Ecuador (mainly in the Sierra) and in Colombia,[135] exclusively in highland locations in the department of Nariño near the border with Ecuador. [109] Guinea pigs are not well suited to environments that feature wind or frequent drafts,[111] and respond poorly to extremes of humidity outside of the range of 30–70%.

The Fairy Caravan, a novel by Beatrix Potter,[127] and Michael Bond's Olga da Polga series for children,[128] both feature guinea pigs as the protagonist. The placement of their eyes. Hey, buddy. The guinea pig's natural diet is grass; their molars are particularly suited for grinding plant matter and grow continuously throughout their life. In the wild guinea pigs are “herd” animals. [93][94] In smaller litters, difficulties may occur during labour due to oversized pups. But, Cavia porcellus is purely a domesticated breed. Alfalfa hay is also a popular food choice and most guinea pigs will eat large amounts of alfalfa when offered it,[21][76] though some controversy exists over offering alfalfa to adult guinea pigs.

[57] While they do not burrow themselves or build nests, they frequently seek shelter in the burrows of other animals, as well as in crevices and tunnels formed by vegetation. [166] Common uses included identification of brucellosis, Chagas disease, cholera, diphtheria, foot-and-mouth disease, glanders, Q fever, Rocky Mountain spotted fever, and various strains of typhus. Guinea pigs that become familiar with their owner will whistle on the owner's approach; they will also learn to whistle in response to the rustling of plastic bags or the opening of refrigerator doors, where their food is most commonly stored. In the case of being scared, the rumble often sounds higher and the body vibrates shortly. [139] Pachamanca or huatia, a process similar to barbecuing, is also popular, and is usually served with corn beer (chicha) in traditional settings.

[122][123] Allergic reactions following direct exposure to guinea pigs in domestic settings have also been reported. [1], The earliest-known European illustration of a domestic guinea pig is a painting (artist unknown) in the collection of the National Portrait Gallery in London, dated to 1580, which shows a girl in typical Elizabethan dress holding a tortoise-shell guinea pig in her hands. The shape of their heads. [73] However, they do not consume all their feces indiscriminately, but produce special soft pellets, called cecotropes (or caecal pellets), which recycle B vitamins, fiber, and bacteria required for proper digestion. [175] Inbred strains are less common and are usually used for very specific research, such as immune system molecular biology. [109] Consistent ambient temperatures in excess of 90 °F (32 °C) have been linked to hyperthermia and death, especially among pregnant sows. Of course, guinea pigs are unique and we love them for it. Happy Cavy Tips. Aside from the common American or English stock, the two main outbred strains in laboratory use are the Hartley and Dunkin-Hartley; these English strains are albino, although pigmented strains are also available.

Studies based on biochemistry and hybridization suggest they are domesticated descendants of a closely related species of cavy, such as C. tschudii, and do not exist naturally in the wild. [87] Additionally, any plant which grows from a bulb (e.g., tulip or onion) is normally considered poisonous,[88] as well as ivy and oak tree leaves. In the 1960s a modern breeding program was started in Peru that resulted in large breeds known as cuy mejorados (improved cuy). Now, there are only six known species of cavia (though scientists still like to debate this). [64] Because of the long gestation period and the large size of the pups, pregnant females may become large and eggplant-shaped, although the change in size and shape varies depending upon the size of the litter.

Wild cavies look very similar to the Agouti guinea pig breed, being a greyish-brown colour with short hair. Organizations devoted to the competitive breeding of guinea pigs have been formed worldwide. [166] They are still frequently used to diagnose tuberculosis, since they are easily infected by human tuberculosis bacteria. African minor livestock species. Females can once again become pregnant 6–48 hours after giving birth, but it is not healthy for a female to be constantly pregnant.
Some are genuine and some are p-dogs or chipmunks.
