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

Daisy is a gorgeous blooming plant with a distinctive white-yellow flower. It’s a lovely flower, but it may not be as “innocent” as it appears, at least to rodents.

Certain daisies contain chemicals that are potentially hazardous to guinea pigs. Some, on the other hand, are not at all poisonous. The issue is that it is difficult to identify exact species of daisies that you are dealing with. I don’t want to risk feeding it to my cavies, so I make sure it’s not in their diet.

Are Daisies Poisonous to Guinea Pigs

Toxic Chemicals

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. 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 used to make botanical insecticides. This type of daisy contains deadly nerve toxins that can be extracted from dried flowers.

Digestion Problems

Due to nutrition and toxicity, daisies can cause problems to the guinea pig’s digestive system. Compounds found in daises 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

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.


Some toxic chemicals found in daisies can cause appetite loss. 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 research on daisies as food for guinea pigs, it’s always best to stay safe and avoid feeding this plant to the guinea pigs.
