The Baldwin guinea pig is a breed developed from a spontaneous genetic mutation in Carol Miller's show-line of white crested golden agouti. [ 1 ] [ 2 ] Though born fully furred, Baldwin guinea pigs begin to lose their fur at two to five days of age, starting at the nose and leaving them almost entirely hairless by about two months of age.

The guinea pig or domestic guinea pig (Cavia porcellus), also known as the cavy or domestic cavy (/ ˈ k eɪ v i / KAY-vee), is a species of rodent belonging to the genus Cavia, family Caviidae. Breeders tend to use the name "cavy" for the animal, but "guinea pig" is more commonly used in scientific and laboratory contexts. [ 1 ]
The montane guinea pig is a medium-sized species, growing to a total length of 247 mm (9.7 in). Their colour varies in different parts of the range; in Peru, the dorsal fur is dark reddish-brown mixed with black, and the underparts are dark buffy-grey; in Chile, the dorsal surface is pale agouti brown with paler underparts; in Bolivia, the upper parts are agouti olive and the underparts creamy ...
A Sheltie guinea pig with lilac and white coloring. Guinea Pigs, also known as cavies (Cavia porcellus), have been domesticated since around (or cicra) 5000 BCE, leading to the development of a diverse array of breeds. These breeds exhibit a wide range of physical characteristics and serve various purposes.
Caviidae, the cavy family, is composed of rodents native to South America and includes the domestic guinea pig, wild cavies, and the largest living rodent, the capybara.They are found across South America in open areas from moist savanna to thorn forests or scrub desert.
This species is both morphologically and genetically similar to Brazilian guinea pigs (Cavia aperea) and Santa Catarina's guinea pigs (Cavia intermedia). The Greater guinea pig is the larger out of all three of these species, with wider upper molars and longer digits. [6] Its karyotype has 2n = 64 and FN = 128. [7]
The male guinea pigs usually have higher masses. The lifespan of these cavies is not well known due to limited data and lack of research; however Moleques do Sul guinea pigs had an average monthly survival rate of (0.81) which is high for a species within a small geographic location. [2]
The modern strain of skinny guinea pig originated from a cross between haired guinea pigs and a hairless lab strain.The hairless strain that it is most likely related to was a spontaneous genetic mutation that was first identified at Montreal's Armand Frappier Institute in 1978, in a colony of Hartley lab guinea pigs.
