Is It Safe For Guinea Pigs To Eat Grapefruit?
Grapefruit is safe for cavies to eat, only if it’s fed to them in moderation.
While this citrus fruit doesn’t contain toxins, it has a high amount of sugar and is quite acidic. This might give your piggy a stomach upset.
Too much sugar being fed to them will cause health issues such as high blood pressure and could lead to obesity. Obesity is common among guinea pigs in captivity because they are housed in cages.
As for the acids in the grapefruit, too much of it could lead to mouth burning and urinary tract infection.

Below are some of the health benefits of feeding grapefruits to your guinea pigs:
Guinea pigs that are in captivity are prone to scurvy disease. Scurvy is a disease caused by a deficiency of vitamin C. Cavys cannot synthesize or store vitamin C in their body. This means they need a source of vitamin C each day.
Without vitamin C, guinea pigs can suffer from painful joints, weight loss, dental issues, bruising or bleeding, diarrhea, and a rough coat.
2-Helps in Digestion
Grapefruit is an excellent source of fiber. Fiber is needed in their diet to help with digestion. 
A good amount of fiber each day helps reduce constipation in guinea pigs. Also, it will help promote regular bowel movement, making food move through the digestive tract smoothly.
3-Rich in Antioxidants
Grapefruit is rich in antioxidants. Antioxidants are essential for guinea pigs as it helps reduce the risk of having diseases.
Free radicals in the body usually cause diseases in cavies. Free radicals are molecules that destroy the cells of the body. These molecules are created by food that the cavies eat, cigarette smoke, and radiation.
By having any food rich in antioxidants like grapefruit, cavys will have less chance of getting sick and having diseases.
