Guinea pig’s water bottle should be cleaned every two days. Apart from this, there are any other health precautions that one needs to take. They also need some fruit and vegetables to give them a source of vitamin C because guinea pigs lack the enzyme to produce this themselves. Melons, oranges and dark green, leafy vegetables like spinach, broccoli, kale and cabbage are all good sources.
Never give your guinea pig lettuce as this can cause diarrhea. Fresh water from a gravity bottle must be available at all times and changed every day. Guinea pigs should not be given rabbit food because they have different nutritional requirements.
