Your vet can also give you some medicine to put in your pets food. This is the most common and potentially damaging cavy disease. It dehydrates your animal and could actualy result in death. It is caused by too much green in your guinea pigs diet. You can easily stop it by feeding your pet less lettuce and other leafy greens, and when you do feed them greens be sure they are crisp and fresh.
Calcium deposits build up in the guinea pigs internal organs, joints, and muscles.
The guinea pig loses weight, has stiff joints, and often dies. This is caused by an imbalance of magnesium, calcium, and phosphorus in the guinea pig. This is why good food is so important. Simply feeding your guinea pig a balanced diet will keep this disease out of your cavy. This is not common, and is preventable.
