Some types of radishes are spicier, while some are sweeter in taste. Now, let’s discuss if our guinea pigs can safely consume radishes.

Can guinea pigs eat radishes? Guinea pigs can eat radishes, but occasionally and in small serving sizes. This is because the radishes contain calcium and sodium, which are the compounds known for causing urinary stones in guinea pigs.

Are Radishes Good for Guinea Pigs Health Benefits

Prevention From Scurvy

Guinea pigs can’t produce vitamin C and a deficit of this vitamin can cause a serious disease called scurvy. Because of that, guinea pigs need foods that are rich in vitamin C.

Luckily, fruits and vegetables are the best sources of this vitamin. Radishes contain some vitamin C that can help prevent scurvy in guinea pigs. Also, vitamin C boosts the immune system and helps to regulate metabolism. This is an essential vitamin for guinea pig’s overall health and well being.

Good Digestion

Radishes have an average amount of dietary fiber that is good for the digestion. They improve bowel movements and the regular emptying of the bowels. So, feeding radishes to guinea pigs will help with digestion and prevent the possibility of constipation and other digestive problems.

Weight Control

The radishes are not really caloric. This means they cannot change the weight of the guinea pig. In short, there is no risk of obesity. Also, radishes have a low amount of carbs and protein too. They won’t provide much energy and this is why they are considered to be diet-friendly veggies. Low amounts of calories, fat, and sugar also help with weight loss.


There are also some antioxidants in radishes that prevent the increase of free radicals in the body of your guinea pigs. Riboflavin, known as the B2 vitamin, is a nutrient that acts as an antioxidant and will convert every food in the body into energy.

Also, it promotes a better flow of oxygen in all of the cells in the organism. Vitamin C is also an antioxidant that controls the threat of free radicals, prevent cell damage, and helps with inflammation in guinea pigs.

Good for Blood and Control of the Blood Pressure

Radishes are low in fat, which is really good. This means that the cardiovascular system will stay in good health. Also, vitamin K in radishes is important for faster blood clotting, in case an injury happens.

The potassium keeps the blood pressure at normal levels. With this, the cardiovascular system will stay healthy.

There is also a small amount of copper that keeps the health of the blood vessels optimal, boosts immunity, and helps in better absorption of the iron. The iron is essential for healthy blood and it fights off anemia as well.

Help Cancer Prevention

Radishes are the part of cruciferous vegetables together with kale, broccoli, cauliflower, cabbage, bok choy, brussels sprouts, and other leafy vegetables that help with cancer prevention. They contain substances known as glucosinolates, and researches believe that they play a role in preventing cancer.

Also, these vegetables are rich in nutrients such as vitamins (vitamin C, vitamin E, and vitamin K), folate, minerals, and some carotenoids (beta-carotene, lutein, and zeaxanthin).

Risks to Consider When Feeding Radishes to Guinea Pigs

Risks to Consider When Feeding Radishes to Guinea Pigs

Bad Digestion

Even though the radishes have a low amount of sugar, it still needs to be regulated. In excess, the sugar will cause very painful digestion for the guinea pig in the form of cramps, loose stool, flatulence, and gasses.

Because of this, don’t give radishes to the guinea pigs very often. The specific spicy and bitter aroma of radishes can also upset the stomach of your little pet.

Urinary Complications

Radishes are rich in calcium. This mineral may help with forming strong bones, but it is not crucial at all for fully grown guinea pigs. In fact, it can cause them urinary problems like stones in kidneys and bladder, blood in urine, and frequent infections of the urinary system.

Otherwise, this mineral forms healthy bone tissues, but only when the guinea pigs are still developing and growing.

The sodium in radishes will do this as well. Studies have shown that 8 out of 10 urinary stones in guinea pigs are caused by huge amounts of calcium and sodium.

Do Guinea Pigs Like Radishes?

Some guinea pigs do like radishes, but most of them will prefer radishes tops or leaves. This is because some guinea pigs will dislike the bitter and spicy taste of radish.

If your guinea pigs don’t like radishes, try giving them a small amount of other rooty vegetables such as carrots, turnips, swede, parsnip, and so on.

Guinea pigs also enjoy leafy vegetables such as spinach, romaine lettuce, red cabbage, kale, and many others. Consequently, it is expected that they prefer radish leaves.

Can Baby Guinea Pigs Eat Radishes?

Baby guinea pigs shouldn’t eat radishes as they need a special diet during that period. Radishes aren’t safe for guinea pigs when they are just babies because the mother’s milk should be the main part of their diet. After some period, you need to introduce them alfalfa hay, pellets, and water.

After a few weeks, you should try to give them some fruits and vegetables and food rich in calcium because it is good for their growth. Also, foods that are rich in vitamin C because it is essential for guinea pig’s growth and overall health.
