Page "Guinea pig" Paragraph 44

Mange mites ( Trixacarus caviae ) are a common cause of hair loss, and other symptoms may also include excessive scratching, unusually aggressive behavior when touched ( due to pain ), and, in some instances, seizures.

Guinea pigs may also suffer from " running lice " ( Gliricola porcelli ), a small white insect which can be seen moving through the hair ; the eggs of these lice, which appear as black or white specks attached to the hair, are sometimes referred to as " static lice ".

Other causes of hair loss can be due to hormonal upsets caused by underlying medical conditions such as ovarian cysts.
