Is Geranium Toxic to Cats and Dogs?
Yes, geraniums are considered toxic to cats and dogs. The American Society for the Prevention of Cruelty to Animals includes plants in the Pelargonium genus, which are commonly known as geraniums, on its list of toxic plants for pets.
All parts of the plant contain compounds that can cause a reaction if a pet eats them. The essential oils can also cause skin irritation on contact. These effects can cause significant discomfort and may require veterinary attention.

What the ASPCA lists for geraniums
The ASPCA’s plant database specifies that geraniums from the Pelargonium genus are toxic to dogs, cats, and horses. The toxicity comes from two primary compounds found in the plant: geraniol and linalool. These are essential oils found within the plant.
If a pet eats a geranium, it may show several clinical signs. The ASPCA lists the following symptoms:
- Vomiting
- Anorexia (loss of appetite)
- Depression
- Dermatitis (skin irritation or inflammation)
Dermatitis can occur from either ingesting the plant or from a pet brushing up against it, which can expose their skin to the irritating oils.
What this means in a home with pets
Having geraniums in a home with cats or dogs introduces a risk of poisoning. Pets, especially younger or more curious ones, may be tempted to chew on the leaves, stems, or flowers. Even a small amount can be enough to cause a negative reaction. Because the plant is a skin irritant, even pets that do not eat it can be affected if they rub against it.
The symptoms of geranium poisoning, such as vomiting and a loss of appetite, can cause discomfort for your pet. Depression or lethargy is another sign that your animal is not feeling well. Responsible pet ownership involves recognizing these risks and taking steps to prevent exposure.
Keeping cats, dogs, and this plant apart
The most effective way to prevent geranium poisoning is to ensure your pets cannot access the plants. For many households, this means not keeping geraniums at all. If you choose to have them, place them in rooms that are completely off limits to pets. Outdoor geraniums should be planted in areas of your yard that your pets cannot reach, such as in fenced off garden beds or high hanging baskets.
Always supervise pets when they are around any plants. If you notice your cat or dog showing interest in a geranium, redirect their attention immediately. Regular supervision helps prevent accidental ingestion. When bringing any new plant into your home, it is a good practice to identify it and check its toxicity to pets.
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 geranium plant or is showing signs like vomiting, lethargy, or skin irritation, contact your veterinarian or a pet poison hotline immediately. Be prepared to tell them what your pet ate, how much, and when it happened. Do not attempt to treat your pet at home without professional guidance.
