Are Tulips Toxic to Dogs and Cats?

Yes, tulips are toxic to dogs and cats. The ASPCA lists them as “Toxic to Dogs, Toxic to Cats, Toxic to Horses,” and notes the “highest concentration of toxin in bulb.” A chewed petal or leaf usually means a mild stomach upset; a bulb is the bigger worry.

What happens if a dog eats tulips

The ASPCA entry for the tulip (Tulipa spp., family Liliaceae) gives “Tulipalin A and B” as the Toxic Principles and “Vomiting, depression, diarrhea, hypersalivation” as the Clinical Signs, followed by “Highest concentration of toxin in bulb.”

Pet Poison Helpline draws the same line between the parts of the plant. “Pet ingestion of small amounts of leaves, stems or flowers may result in mild nausea with vomiting.” Bulbs are different: “Consumption of bulb material poses risk for persistent gastrointestinal distress (e.g., vomiting, loss of appetite, diarrhea, drooling) and lethargy.”

That makes the garden the main place to watch. A dog that digs in a freshly planted bed, or finds a bag of bulbs in the garage, reaches the part of the plant with the most toxin. Pet Poison Helpline’s page covers tulips and hyacinths together, so treat a bag of mixed spring bulbs the same way.

What happens if a cat eats tulips

The ASPCA lists cats as affected, with the same signs. Pet Poison Helpline’s note on small amounts of leaves, stems or flowers (mild nausea with vomiting) applies to cut tulips in a vase too.

One point worth knowing: the ASPCA files tulips in the Liliaceae family, the same family as lilies. The kidney failure that makes lilies so dangerous for cats is tied to the Lilium and Hemerocallis plants, which Merck says are the true lilies. Tulips are not true lilies by that definition, and the ASPCA’s tulip entry doesn’t list kidney failure. Mixed bouquets are the catch, so if a cat chewed one and you can’t rule out lilies, treat it as a lily emergency (lilies and cats).

Signs to watch for

• Vomiting
• Diarrhea
• Drooling (hypersalivation)
• Loss of appetite
• Depression or lethargy: a pet that is unusually quiet or tired

What to do

1. Figure out what was eaten: flower, leaf or bulb, and roughly how much.
2. Call your vet or a poison line: ASPCA Animal Poison Control (888) 426-4435 or Pet Poison Helpline (855) 764-7661 (a fee may apply).
3. Bring a bulb or a photo if your vet wants to see your pet.
4. Don’t wait for vomiting if a whole bulb is missing; call as soon as you notice.

A pet poison emergency card keeps both numbers on the fridge, and the dog first-aid checklist helps you stock the rest.

Keeping bulbs and pets apart

Store bulbs in a closed cupboard, not an open bag on the floor. Plant when your dog is inside, and fence or cover new beds until the soil settles. Other garden plants worth checking are azaleas, which can affect the heart, and the sago palm, which can cause liver failure. Indoors, the ASPCA lists the spider plant as non-toxic to dogs and cats.
