I've been feeding these diets to my guinea pigs since the summer of 2016, I'd decided that doing research into natural diets was going to be very beneficial to my guinea pigs and their health. I am in no way a nutritionist but I have thoroughly researched natural diets from a range of reliable sources, so this page should give you a fairly accurate indication of what to feed. Of course these diets are able to be adapted and I understand that this isn't a possible diet for everyone. The pie charts below are not based on percentages, they are just a way of showing roughly how much of each food I provide.
