Guinea Pig Myths Busted: Things You Never Knew About Guinea Pigs

In this episode of The Consult Room, we’re continuing the “Things You Never Knew” series - and this time, we’re talking all things guinea pigs. Guinea pigs are widely kept across the UK, but they’re also one of the most misunderstood pets. They’re often seen as easy, low-maintenance “starter pets” for children - but the reality of their diet, biology, social needs and healthcare is very different. In this episode, Annie and I bust some of the biggest myths around guinea pig care. We explore why they should never be kept alone, why hay is so important for their teeth and digestion, and the unusual biological reason they need vitamin C every single day. We also unpack some of their stranger behaviours - from popcorning and wheeking to eating caecotrophs - and explain why these natural prey animals can be incredibly good at hiding signs of illness. Because guinea pigs might be small, but giving them the life they deserve requires far more knowledge and commitment than many people realise.
