Diet: Commercial guinea pig pellets should make up the bulk of your pet’s diet. Nutritionally complete, and are made from plants, seeds and veggies. Feed your guinea pigs twice daily, in the morning and in the evening. Offer small amounts of fresh fruit and vegetables to your guinea pigs every day. Guinea pigs can not manufacture their own vitamin C, so fresh vegetable will help with that. Try grapes, cucumbers, corn, peas, carrots and pears. Half a handful of veggies and a slice of fresh fruit per pig is plenty. Always make sure to clean up any leftover fresh food before it spoils. You’ll also need to make hay available to your pets at all times. It’s great for the digestive system, and will also satisfy your pet’s need to gnaw. Fresh, clean water should be available at all times. Use an inverted bottle with a drinking tube, and change the water daily.
Housing: Guinea pigs need a minimum of eight square feet of floor space in their cages. They are very social and will be happier if housed with another guinea pig, but this doubles the amount of space that they will need in their cages. Guinea pigs have sensitive paw pads and need solid flooring. They cannot be housed in a wire-bottomed cage.
When guinea pigs are frightened, they either freeze in place or run away, and they prefer to have a hiding place in their cage. Plastic tubes and wooden boxes are available. Many guinea pigs love to chew. Small pieces of untreated wood can also be provided to help satisfy your guinea pig’s need to chew and keep their teeth from getting overgrown as well.
Paper bedding should be several inches thick and should be changed twice weekly. Cedar shavings should not be used as bedding, as they contain phenols, which can be harmful to guinea pigs. Remove soiled bedding, droppings and stale food from the cage daily. Clean the cage completely once a week by replacing dirty bedding and scrubbing the bottom of the cage with warm water. Be sure everything’s dry before adding fresh bedding.
Make sure that your guinea pig doesn’t get overheated or chilled, as they are susceptible to both. In general, if you are comfortable, they are probably at a safe and comfortable temperature.
