Chris and Angie explore the fascinating world of guinea pigs (cavies), featuring a visit to Chris’s New Zealand pets, Thor and Prince, with special guest Pip. They unpack what makes guinea pigs unique — tailless rodents with continuously growing teeth, wide vision, sensitive hearing, and a grazing digestive system that requires constant hay and daily vitamin C.
The episode dives into their South American wild relatives and conservation status (including the critically endangered Cavia intermedia), their 5,000–7,000-year domestication in the Andes, and their unexpected role in vitamin C and biomedical research. You’ll also learn why they’re social herd animals that should never live alone, plus practical care tips on housing, diet, temperature, and health.
From popcorning and complex vocalizations to precocial babies and surprising physiology, this episode reveals why guinea pigs are far more biologically impressive than their “starter pet” reputation suggests.
