All my piggies have a good varied diet. They have dried guinea food with added vitamin c daily. They also have plenty of fresh meadow hay daily, to aid there digestive system. It is wise to pick hay that has been dust extracted as this can cause respiratory problems. Readi grass is also available daily. It is essential that guinea pigs have a good source of vitamin c if they can suffer numerous problems and even die, therefore a vitamin c supplement is added to there fresh water daily, and fresh vegtables given 3-4 times a week. The fruit and veg that my guineas like is numerous but there favourites are below:
Sping greens
Carrots
Parsley
Brussels
Cucumber
Grapes (especially good when pregnant for the sugar level)
Apple (occaisionaly as they can suffer scabs on there lips due to the acid levels)
Melon
Cauliflower leaves
