Spring plants and garden products can harm pets, but the risk depends on the exact species or ingredient, the amount, and how the pet encountered it. If your pet may have eaten a dangerous plant or product, call a veterinarian or animal poison-control service promptly—do not wait for severe symptoms. For a cat that may have eaten a true lily or daylily, seek emergency veterinary care immediately.
What to do after a suspected exposure
- Contact a veterinarian or animal poison-control service promptly. Known or suspected lily or daylily ingestion in a cat is an emergency, even if the cat seems well. Pet Poison Helpline advises bringing the cat and plant to a veterinarian. Pet Poison Helpline’s lily guidance explains the danger.
- Identify what was involved. Note the animal species, exact plant or product name, estimated amount, time of exposure, plant part (such as bulb, leaf, flower, or pollen), route of exposure, and any signs you see. For a garden product, keep its package or photograph the ingredient label; for a plant, retain a sample or clear photo if you can do so safely.
- Follow professional advice. These details help a veterinarian or poison-control professional assess the exposure. Do not use symptoms alone to guess the toxin or delay the call while trying to identify it.

Which spring plants are dangerous to pets?
Common names can be misleading: “lily” does not identify one plant or one level of risk. Verify the exact plant with a species-specific reference. The ASPCA notes that its toxic and non-toxic plant list is not all-inclusive, so absence from a list does not establish that a plant is safe. Its toxic and non-toxic plant database can help with identification.
| Plant or group | What changes the risk | Reported concerns |
|---|---|---|
| True lilies and daylilies | Especially urgent for cats. Do not assume peace, calla, or Peruvian lilies are true lilies; these are different plants and may cause different effects. | True lily or daylily ingestion can cause severe kidney injury or failure in cats and may be fatal. Treat a suspected cat exposure as urgent. Pet Poison Helpline |
| Tulips and hyacinths | Toxins are concentrated in the bulbs, making digging or bulb ingestion a particular concern. | Oral irritation, drooling, vomiting, and diarrhea; larger bulb ingestions can cause more serious signs. ASPCA’s spring gardening guidance |
| Daffodils (narcissus) | The bulbs are especially toxic. | Drooling, vomiting, and diarrhea; larger ingestions may lead to depression, low blood pressure, seizures, or other severe effects. ASPCA |
| Iris | ASPCA lists iris as toxic to cats and dogs. | Vomiting, diarrhea, and drooling. ASPCA |
| Crocus | Distinguish spring crocus from autumn crocus, Colchicum autumnale; they are not the same risk category. | Spring crocus is associated with gastrointestinal upset. Autumn crocus can cause severe vomiting, bleeding, liver or kidney damage, and respiratory failure; signs may be delayed. Pet Poison Helpline’s autumn crocus guidance |
How to interpret symptoms
Drooling, vomiting, diarrhea, abdominal discomfort, lethargy, and weakness are reported across plant exposures, but they do not identify which toxin was involved. Depending on the plant or product, serious exposure can also affect the heart, breathing, kidneys, liver, or nervous system, and can lead to seizures or collapse. The substance and dose—not the symptom list alone—determine the risk. FDA guidance notes that toxicity varies with the animal, amount, and plant part; see FDA’s information on pets and toxic plants.
Fertilizers, pesticides, and other garden products
Garden products are not interchangeable: the formulation, ingredient, amount, and route of exposure matter. Fertilizers can cause gastrointestinal irritation or more serious illness. Bone meal may attract dogs and form a mass in the stomach; blood meal can also cause illness. Depending on formulation, fertilizer exposures can involve pancreatitis, obstruction, iron poisoning, or severe toxicity. Pesticides, insecticides, and weed killers range from products that cause irritation to exposures that can be life-threatening. Follow the label and keep pets away during application and until the product directions say they can return. The ASPCA’s spring gardening guidance and FDA’s toxic-plant guidance describe why product and exposure details matter.
What information helps a professional assess the exposure?
There is no reliable home scoring system for deciding whether an exposure is harmless. A veterinarian or poison-control professional needs the details in combination:
Rank #2
- Active Ingredient Formula: Contains Boric Acid 20.0% as the effective insecticide component for eliminating silverfish infestations
- Versatile Indoor Application: Designed for use in residential housing including indoors, attics, basements, closets, bookcases, around household clothing and fabric containers, drawers, rugs and carpets
- Coverage and Application Rate: Apply at approximately 2 oz per 100 square feet or 1 quart per 250 square feet for effective silverfish control
- Convenient Pack Format: Comes in packs of 24 to protect your entire house, restaurant, or commercial building with odorless powder formula
- Long-Lasting Protection: Each application works for up to 4 weeks, with simple placement of 2-3 packs in affected areas where 3 packs can cover up to 100 sq. ft. of enclosed space
- Animal species (dog, cat, or another animal)
- Exact plant species or product name and, for products, ingredients on the label
- Estimated amount and time of exposure
- Plant part involved, or route of product exposure
- Current signs and when they began
FDA and Pet Poison Helpline guidance emphasizes that risk changes with these variables. Share what you know, say what remains uncertain, and let a professional direct the next steps.

How to prevent spring garden exposures
- Verify the exact plant before bringing it into the home or garden; do not rely on a broad common name such as “lily.”
- Keep pets away while applying fertilizers, insecticides, or other garden products, and follow the product label.
- Store garden products in their original labeled, tightly sealed containers, out of pets’ reach.
- Where feasible, fence off areas where toxic plants are grown.
- Remember that even plants listed as non-toxic may upset a pet’s stomach if eaten, and plant databases may not include every species.
ASPCA’s springtime gardening tips offer additional prevention guidance.
