Cavia porcellus

  • The guinea pig (Cavia porcellus), also commonly called the Cavy, is a species of rodent belonging to the family Caviidae and the genus Cavia. Despite their common name, these animals are not pigs, nor do they come from Guinea.
  • They originated in the Andes, and studies based on biochemistry and hybridization suggest they are domesticated descendants of a closely related species of cavy such as Cavia aperea, C. fulgida, or C. tschudii, and therefore do not exist naturally in the wild.The guinea pig plays an important role in the folk culture of many Indigenous South American groups, especially as a food source, but also in folk medicine and in community religious ceremonies.Since the 1960s, efforts have been made to increase consumption of the animal outside South America.

As A Pet

  • In Western societies, the guinea pig has enjoyed widespread popularity as a household pet since its introduction by European traders in the 16th century. Their docile nature, their responsiveness to handling and feeding, and the relative ease of caring for them, continue to make the guinea pig a popular pet. Organizations devoted to competitive breeding of guinea pigs have been formed worldwide, and many specialized breeds of guinea pig, with varying coat colors and compositions, are cultivated by breeders.

Scientific research

  • Biological experimentation on guinea pigs has been carried out since the 17th century. The animals were frequently used as a model organism in the 19th and 20th centuries, resulting in the epithet "guinea pig" for a test subject, but have since been largely replaced by other rodents such as mice and rats. They are still used in research, primarily as models for human medical conditions such as juvenile diabetes, tuberculosis, scurvy, and pregnancy complications

Hamster
  • Etymology of name
  • The name hamster derives from the German Hamster, which itself comes from earlier Old High Germanhamustro. Possibly related to Old Russianchoměstrǔ, which is either a blend of the root of Russiankhomiak "hamster" and a Baltic word (cf. Lithuanianstaras "hamster")or of Persian origin (cf. Avhamaēstar "oppressor")

Hamsters are rodents belonging to the subfamilyCricetinae. The subfamily contains about 25 species, classified in six or seven genera.[1]
  • Hamsters are crepuscular. In the wild, they burrow underground in the daylight to avoid being caught by predators. Their diet contains a variety of foods, including dried food, berries, nuts, fresh fruits and vegetables. In the wild they will eat any wheat, nuts and small bits of fruit and vegetables that they might find lying around on the ground, and will occasionally eat small insects such as small fruit flies, crickets, and meal worms. They have elongated fur-lined pouches on both sides of their heads that extend to their shoulders, which they stuff full of food to be stored, brought back to the colony or to be eaten later.

Although the Golden Hamster (Mesocricetus auratus) was first described scientifically in 1839, it was not until 1930 that researchers were able to successfully breed and domesticate hamsters.[2] Pet Syrian hamsters are descended from hamsters first found and captured in Syria by zoologist Israel Aharoni.
  • Hamster behaviour can vary depending on their environment, genetics, and interaction with people. Because they are easy to breed in captivity, hamsters are often used as lab animals in more economically developed countries. Hamsters have also become established as popular small house pets.
