Since your pet is more active at night, he requires quiet periods during the day for rest. Place the cage in an area free of noise, commotion and excitement. Guinea pigs tolerate cool temperatures better than heat. High heat coupled with high humidity may cause heat stroke. Keep the cage out of direct sunlight in a room with a temperature range of 65 to 75 degrees Fahrenheit.
All guinea pigs MUST have vitamin C (ascorbic acid) added to their diet. Their bodies, like the human body, cannot manufacture the vitamin. Although commercial pellets add vitamin C, the potency is often lost within five to six weeks from the date on the package. Assume that your pet is not getting enough vitamin C and supply vegetables and fruit such as guava, orange and lemon with peel, parsley, brussel sprouts, broccoli, collards, mustard greens and kale all of which have 20 mg of vitamin C or more per ounce.
