Can Guinea Pigs Eat Daisies? (Risks, Nutrition Facts & More)

Guinea pigs are one of the most popular small house pets mainly because they are budget-friendly, happy vegetarians! A herbivore pet can eat fruits, veggies, herbs, roots, or even some flowers! Yes, almost everything that grows from the ground.

Daisies, for example, are beautiful flowering plants that have a nice white-yellow flower all of us know. In this article, you will learn are daisies edible for guinea pigs. Daisy is a pretty flower, but it might not be so “innocent-looking” after all, at least for rodents.

Can guinea pigs eat daisies? Guinea pigs can’t eat daisies because certain types of daisies contain chemicals that may be toxic to guinea pigs. Some types of daisies can be toxic to guinea pigs even if they consume just a small amount of them. On the other hand, some of them are not toxic at all. So, if we talk in general, daisies are a risky food for the guinea pigs and should be avoided.

Some of the side-effects of daisy toxicity are nausea, vomiting, stomach pains, diarrhea, contact dermatitis, and allergic reactions. Even though flowers are technically safe for herbivores, most flowers have toxins that can harm guinea pigs.

Guinea pigs can eat dandelions, for example, but daisies are the opposite. Don’t get us wrong there are daisies that are safe but as it is extremely difficult to differentiate them, it is best to simply avoid them. It’s just a riskier option.

In the following sections, we will explain more about the nutrition facts of daisies and the risks of feeding daisies to guinea pigs. Let’s start!

Are Daisies Poisonous to Guinea Pigs? | Possible Risks

Are Daisies Poisonous to Guinea Pigs

Sadly, there is not enough factual research or proven way to show how toxic it is for guinea pigs. But we have found some studies about daisy toxicity on animals in general. Let’s begin!.

Toxic Chemicals

First of all, there are several chemicals in daisies that can cause serious health problems in guinea pigs. The first chemicals are sesquiterpene lactones, usually found in plants of the family Asteraceae (daisies are part of this family). Sesquiterpene lactones can be toxic and irritant for animals and cause different health problems.

Other compounds in daisies are toxins known as pyrethrins. These toxins are found in the Pyrethrum daisy (Chrysanthemum cinerariifolium) used to make botanical insecticides. This type of daisy contains deadly nerve toxins that can be extracted from the dried flowers.

Due to that, daisies can be very dangerous to guinea pigs and other mammals. These toxins have the ability to be absorbed in the bloodstream, which can lead even to death.

Digestion Problems

Due to nutrition and toxicity, daisies can cause problems to the guinea pig’s digestive system. Compounds found in daises mentioned above can lead to serious stomach pains, flatulence, gas, bloating, nausea, constipation, diarrhea, vomiting, and bleeding within the digestive tract.

If the guinea pig eats some of the toxic daisies, don’t panic. Simply give them a lot of water and take the guinea pigs to the vet if you notice any strange symptoms.

Allergic Reactions

The scariest risk is an allergic reaction. As we have said, this plant apparently has some powerful components that can cause severe allergies in guinea pigs.

The sesquiterpene lactones may be very irritating to the guinea pig’s nose, eyes, mouth, and skin. Also, these components can cause allergic contact dermatitis, swelling, or irritation in the throat.

The pyrethrum component is also very dangerous. It can lead to excessive drooling, muscle spasms, respiratory problems, breathing difficulties, gagging or choking, vomiting, diarrhea, shaking, paralysis, and even death. All of the symptoms are indicators of allergic reactions in guinea pigs.

Urinary Problems

The amount of calcium in daisies can lead to serious urinary problems in guinea pigs. That’s because an excess of calcium in food causes bladder or kidney stones. Some of the bladder and kidney stones symptoms are darkened urine, blood in urine, pain during urination, weight loss, etc.

It’s good to know that calcium is important for young guinea pigs when they are growing, and because of that, baby guinea pigs have a special diet. But, for adult guinea pigs, calcium can be a real treat, so our adult guinea pigs need food that is low in calcium.


Some toxic chemicals found in daisies can cause appetite loss, and due to that, guinea pigs can suffer from weight loss and anorexia. If you ever notice that your guinea pig won’t eat or suffers from weight loss, it is important to visit a vet as soon as possible.

Also, with the lack of detailed researches for daisies as food for guinea pigs, it’s always best to stay safe and avoid feeding this plant to the guinea pigs.
