Some Daisies Are Toxic to Cats — But Not All
The answer to whether daisies are toxic to cats depends entirely on which type of daisy you are talking about. The common term “daisy” covers dozens of different plant species across multiple genera, and their toxicity to cats varies significantly. Some daisies are genuinely dangerous, while others pose little to no risk.
The most important varieties to know about: Chrysanthemum daisies (including Shasta daisies and garden mums) contain pyrethrins and sesquiterpene lactones that are toxic to cats with a mild to moderate severity rating. Meanwhile, African daisies (Osteospermum) and Gerbera daisies are considered non-toxic to cats by the ASPCA.
Because “daisy” is used so loosely in garden centers and floral shops, identifying exactly which plant you have is the critical first step. This guide will help you sort through the most common varieties, understand the symptoms of daisy poisoning in cats, and know what to do if your cat ingests the wrong kind.
Which Daisy Varieties Are Toxic to Cats?
Let’s break down the most common daisy types by their safety profile for cats. This section will help you identify what you have growing in your garden or sitting in a vase on your kitchen table.
Toxic Daisy Varieties
Chrysanthemums (Chrysanthemum spp.): Often sold as “mums” or “daisies,” chrysanthemums contain pyrethrins (natural insecticidal compounds), sesquiterpene lactones, and other irritating substances. They are toxic to cats, causing gastrointestinal upset, drooling, and skin irritation. This is the most common toxic “daisy” that cat owners encounter.
Shasta Daisy (Leucanthemum x superbum): Formerly classified under Chrysanthemum, Shasta daisies belong to the same family and contain similar irritating compounds. They should be treated as toxic to cats, with symptoms similar to chrysanthemum ingestion.
Seaside Daisy (Erigeron glaucus): While less commonly encountered, seaside daisies also contain compounds that can cause mild gastrointestinal irritation in cats.
Chamomile (Matricaria chamomilla and Chamaemelum nobile): Often grouped with daisies due to their similar appearance, chamomile plants are toxic to cats. They contain bisabolol, chamazulene, and volatile oils that cause vomiting, diarrhea, and contact dermatitis.
Non-Toxic Daisy Varieties
Gerbera Daisy (Gerbera jamesonii): The popular, large-bloomed gerbera daisy is listed as non-toxic to cats by the ASPCA. These colorful flowers are a safe choice for bouquets and gardens in cat households.
African Daisy (Osteospermum spp.): These hardy garden daisies are not toxic to cats. They come in vibrant purples, pinks, and whites and are a great cat-safe alternative.
When in doubt, check the botanical (Latin) name on the plant tag. Common names can be misleading, but the botanical name will help you determine exactly which species you have and whether it poses a risk.
Symptoms of Toxic Daisy Ingestion in Cats
If your cat eats a toxic daisy variety — particularly a chrysanthemum or Shasta daisy — symptoms typically appear within a few hours. The pyrethrins and sesquiterpene lactones in these plants affect the gastrointestinal system and can also cause skin reactions.
Gastrointestinal symptoms:
- Vomiting
- Diarrhea
- Drooling and excessive salivation
- Loss of appetite
- Abdominal discomfort
Dermatological symptoms:
- Skin irritation or rash (contact dermatitis), especially on the face and paws
- Redness around the mouth and nose
- Excessive scratching or grooming of affected areas
Neurological symptoms (rare, usually with large ingestions):
- Incoordination or wobbliness
- Muscle tremors
- Excessive agitation or restlessness
The pyrethrin compounds found in chrysanthemums deserve special attention. Pyrethrins are the basis for many commercial insecticides, and cats are notably sensitive to these chemicals. While the concentration in a live chrysanthemum plant is much lower than in a concentrated insecticide product, cats who consume a large quantity may exhibit more pronounced neurological symptoms.
In the vast majority of cases, toxic daisy ingestion causes mild to moderate symptoms that resolve within 24 to 48 hours with supportive care. Severe reactions are uncommon but can occur in cats who eat a large amount or who have heightened sensitivity to the compounds.
What to Do If Your Cat Eats a Toxic Daisy
Contact your veterinarian or the ASPCA Animal Poison Control Center (888-426-4435) if you believe your cat has eaten a chrysanthemum, Shasta daisy, chamomile, or any other potentially toxic daisy variety. Even though the toxicity is generally mild, professional guidance helps you assess whether home monitoring is sufficient or a vet visit is warranted.
Steps to take immediately:
- Remove the plant from your cat’s reach to prevent further ingestion.
- Identify the daisy variety if possible. Check the plant tag, take a photo, or bring a sample to your vet. Knowing the exact species helps determine the level of risk.
- Rinse any sap from your cat’s fur or skin using a damp cloth and lukewarm water. This is especially important if you notice irritation on the paws, face, or mouth.
- Offer fresh water to help flush the system and keep your cat hydrated.
- Monitor symptoms for the next 24 hours, keeping notes on vomiting frequency, appetite, and behavior.
If your vet recommends a clinic visit, treatment will likely include anti-nausea medication to stop vomiting, fluid therapy to address dehydration, and possibly activated charcoal if ingestion was recent and significant. For skin reactions, gentle cleansing and a topical soothing agent may be applied.
Most cats recover fully from toxic daisy ingestion without lasting effects. The key is to act quickly, get professional advice, and provide supportive care during recovery.
Preventing Daisy-Related Problems for Your Cat
A few simple strategies can help you enjoy daisies — or avoid the risky ones entirely — while keeping your cat safe.
Choose non-toxic varieties. If you love the daisy look, stick to gerbera daisies and African daisies for both your garden and indoor arrangements. They provide the same cheerful aesthetic without any toxic risk.
Label your garden plants. Keep the nursery tags from your plants or create your own labels. When you know exactly what is growing in your garden, you can quickly assess the risk if your cat shows interest in a particular plant.
Be cautious with mixed bouquets. Florists often include chrysanthemums in mixed flower arrangements. If you receive flowers, check the contents before placing them where your cat can reach. When in doubt, display bouquets in a closed room or on a stable, high surface.
Provide safe plants for your cat. Cats often chew on plants out of curiosity or a desire for roughage. Offering cat grass, catnip, or silver vine gives them a safe, appealing alternative that can reduce their interest in your decorative plants.
Garden with cat safety in mind. If you maintain a garden and have an outdoor or indoor-outdoor cat, familiarize yourself with the toxicity of every plant in your space.

Gerbera Daisies: The Cat-Safe Choice
Gerbera daisies deserve their own spotlight as the ideal daisy for cat households. Listed as non-toxic by the ASPCA, gerbera daisies offer bold, vibrant blooms in nearly every color imaginable — red, orange, yellow, pink, white, and even bicolored varieties.
These flowers are popular as both garden plants and cut flowers. They have a long vase life, making them excellent for indoor displays. Because they are completely safe for cats, you can place gerbera daisy arrangements on tables, countertops, and anywhere else without worry.
In the garden, gerbera daisies thrive in full sun with well-drained soil. They are perennial in warmer climates (USDA zones 8-11) and can be grown as annuals elsewhere. Their large, vivid flowers attract butterflies and bees, adding ecological value to your garden alongside their visual appeal.
If you are welcoming a new cat into your home and want to make your space pet-safe, swapping toxic daisies for gerberas is one of the easiest changes you can make. Visit our cat adoption hub for more tips on preparing your home for a feline companion.
Frequently Asked Questions
Are all chrysanthemums toxic to cats?
Yes. All species and cultivars within the Chrysanthemum genus contain pyrethrins and sesquiterpene lactones that are toxic to cats. This includes garden mums, florist chrysanthemums, and Shasta daisies. The severity is generally mild, but cats should not have access to any chrysanthemum variety.
My cat sniffed a daisy but did not eat it. Is that dangerous?
Simply sniffing a daisy is extremely unlikely to cause any problems. Toxic effects require actual ingestion or, in some cases, prolonged skin contact with plant sap. If your cat only sniffed the flower and walked away, there is no cause for concern.
Can daisies cause allergic reactions in cats separate from toxicity?
Some cats may have allergic reactions to plant pollen, including daisy pollen, that are distinct from toxicity. Signs of a pollen allergy include sneezing, watery eyes, and skin irritation. If your cat frequently shows these symptoms around blooming plants, talk to your veterinarian about allergies.
Are daisy essential oils safe to use around cats?
Essential oils derived from chrysanthemums or chamomile should be used with extreme caution around cats, and many veterinarians recommend avoiding them entirely. Cats lack certain liver enzymes needed to metabolize essential oil compounds, making them highly susceptible to toxicity from diffused or topically applied oils. Always consult your vet before using any essential oils in a home with cats.
How can I tell the difference between a chrysanthemum daisy and a gerbera daisy?
Gerbera daisies have a single layer of large, wide petals radiating from a prominent central disc, and they grow on thick, leafless stems. Chrysanthemum daisies tend to have multiple layers of thinner petals (sometimes pom-pom shaped) and grow on leafy, branching stems. If you are unsure, check the plant’s botanical name on its nursery label.
