Cavies are easy to care for and keep healthy as long as they are fed a high-quality diet and kept clean. They originate from an area where the temperatures stay fairly constant, so fluctuations in temperature are not ideal. Cavies must be kept indoors. They do not tolerate high temperatures. Good ventilation is important at all times.
Skinny Pigs should not be housed at temperatures below 60 degrees F. They should not be placed where they will be exposed to direct sunlight as they can sunburn. As long as they are kept out of drafts, fed a good diet and kept clean, they are just as hardy as cavies with fur.
All cavies do best at temperatures between 60 and 75 degrees F.
Cavies do not manufacture their own vitamin C, so their diet must contain this vitamin. Use a high-quality guinea pig pellet that is fresh. Do not feed mixes that contain seeds as the cavy can choke on them. My cavies enjoy a chewable vitamin c supplement daily. You can find quality ones at http://www.oxbowhay.com/. I use a chewable vitamin c tablet made for human consumption. I break the 500-mg tablet into four pieces and give each piggie one.
Hay is very important for proper digestion, nutrition and entertainment. Only feed alfalfa hay to babies and pregnant females. Quality timothy hay is best, but orchard grass and other non-legume grass hays are good.
Feeding nutrient-rich greens daily is also a good part of a healthy diet. Do not feed iceburg lettuce as it contains little nutrients and a lot of water. I feed mine kale, parsley, collard greens, turnip greens, red leaf lettuce, green leaf lettuce, and each one gets a baby carrot a couple times a week. They will also eat radishes, bell pepper, zuchinni, and turnips! About a half-cup of fresh veggies per day is enough per pig.
