Fresh leafy green vegetables and herbs
Offer a variety of fresh leafy green vegetables & herbs daily. Some examples of these include dark leafed lettuce varieties such as rocket, dandelion greens, snow peas, and herbs such as marjoram, borage, marigold, nasturtium, rosemary, parsley, coriander, basil, and dill. Other foods that are good to fed guinea pigs a few times a week include broccoli, cabbage, endive, carrot tops, Brussels sprouts, kale, silver beet, mint, and fruits such as apples (but with no seeds), mango, and papaya.
Guinea pigs need vitamin C
Provide your guinea pigs with a dietary source of vitamin C because (like humans), guinea pigs cannot synthesise vitamin C from other food substances. Vitamin C rich foods such as leafy green veggies and capsic*ms (green, orange, and red) should be fed to your guinea pigs daily. Foods like carrots, kiwifruit, berries, and pineapple are also great as a source of vitamin C and a tasty treat for your guinea pigs but only feed them a few times a week, not every day, as these foods have quite a high sugar content.
Keep treats to a minimum
High quality commercial ‘Guinea Pig’ pellets (minimum 16% fibre content) may be offered in small quantities, but these should not form the main part of the diet. Although many contain adequate levels of Vitamin C when fresh, this is only when the food is very fresh and within just a few months these foods no longer contain Vitamin C.
