Physiologic Norms and Biologic Data

Norms vary slightly from one source to another. Additional sources welcome. Feel free to contact us with additional information.

Note: the personal experiences of hundreds of guinea pig owners indicate a wide range of weights. Male and female weights are similar and the average weight of a mature guinea pig is greater than the values reported by these sources. Experience also suggests guinea pigs can be sexually mature as early as 3 1/2 weeks of age. Be sure to separate male pups from all females at 3 weeks of age.
