Is Foxglove Toxic to Cats and Dogs?
Yes, foxglove is toxic to cats and dogs. According to the ASPCA, the entire plant, from its flowers to its roots, contains substances that are dangerous for pets if ingested. This popular garden plant, known scientifically as Digitalis purpurea, can cause severe health problems for animals.
The toxic compounds in foxglove are cardiac glycosides. Even a small amount can have a significant impact on a pet’s health. It is crucial for pet owners to recognize this plant and prevent their animals from coming into contact with it, whether it is growing in a garden, brought inside as part of a floral arrangement, or disposed of after pruning.

What ASPCA lists for foxglove
The ASPCA identifies foxglove as toxic to cats, dogs, and horses. The danger comes from its toxic principles, which are identified as cardiac glycosides. These compounds can seriously affect an animal’s heart and other body systems.
If a pet eats any part of the foxglove plant, the ASPCA notes that a range of serious clinical signs may develop. Pet owners should watch for:
- Vomiting
- Diarrhea
- Weakness
- Cardiac arrhythmias
In severe cases, ingestion can lead to cardiac failure and may even be fatal. The severity of the reaction can depend on how much of the plant was eaten. All parts of the foxglove are considered dangerous.
What this means in a home with pets
Having foxglove in or around a home requires careful management to protect pets. Because the entire plant is toxic, animals should not be allowed to chew on the leaves, stems, flowers, or roots. Even the water in a vase holding foxglove cuttings can contain the toxic compounds and be harmful if a pet drinks it.
Puppies and kittens, known for their curiosity, may be at a higher risk of accidental ingestion. Supervising pets when they are outdoors in a yard or garden with this plant is a key safety measure. If you have foxglove in your garden, be mindful of where fallen leaves or flowers land, and dispose of any plant trimmings in a secure bin that pets cannot access.
Keeping cats and dogs and this plant apart
Prevention is the most effective way to keep pets safe from foxglove poisoning. If you have this plant in your garden, consider creating a physical barrier, such as fencing, to keep pets out of the area where it grows. You might also choose to remove the plant entirely or replace it with a non-toxic alternative if you have pets that tend to chew on plants.
For indoor safety, never bring foxglove into your home for floral displays. If you receive a bouquet that contains it, it is safest to remove the foxglove before displaying it. Always read plant labels carefully when purchasing new plants for your home or garden to ensure they are safe for your specific pets. Introducing new items to a pet’s environment should always be done with supervision.
When to call your vet
If your pet chewed or ate part of this plant, call your veterinarian or an animal poison control line. Note which plant and which part, how much may be gone and when, and take a photo or a piece of the plant with you.
If you suspect your cat or dog has eaten any part of a foxglove plant, contact your veterinarian or the ASPCA Animal Poison Control Center immediately. Do not wait for symptoms to appear. Have the plant’s name and any available packaging ready, and try to estimate when your pet ate the plant and how much was consumed.
