Really enjoying these videos. Shame they aren't longer really. The lady should have mentioned about their inability to produce vitamin c (like us humans) which can lead to scurvy and poor immune system and the probiotics which are available to be added to water as well as mentioning why guinea nuggets are good because they contain vit c.
The videos are short and sweet, but we have lots more information on the yourguineapig website which covers all areas of guinea pig care - so you can read more in-depth information by clicking this link www.yourguineapig.co.uk
The 'feeding your guinea pig' section covers their inability to produce vitamin C and recommends foods you can give them that are rich in vitamin C.
