Poisonous Plants for Cats and Dogs

Keep an eye out for some of the more common poisonous plants for cats and dogs to avoid this spring and all year round.

toxic plants for pets

1. Sago Palm

Sago palm

Sago palm trees are common in tropical and subtropical environments, but many are surprised to learn they’re one of the more toxic plants for cats and dogs. When eaten, the sago palm can wreak havoc on your pet. Symptoms are appropriately alarming: Vomiting, diarrhea, and seizures are just a few indicators that your pet is experiencing acute palm poisoning. Even if your pet isn’t experiencing symptoms, getting to a vet right away is important. Liver damage can occur if left untreated.1

2. Azaleas

Azaleas

These spring-blooming flowers come in many types and colors, but there’s one thing they all have in common: They’re extremely toxic plants for pets and should be avoided at all costs. Even the smallest nibble of azaleas can lead to serious poisoning in dogs and cats. Symptoms include vomiting, diarrhea, excessive drooling, loss of appetite, weakness, and, in extreme cases, transient blindness and comas.3

3. Mushrooms

Mushrooms

Wild mushrooms are a danger to any pets who spend a lot of time outdoors. Although only certain types of mushrooms are toxic, it takes a trained eye to be able to spot the difference. Besides, by the time a hungry hound or curious cat gets a surprise mouthful, it’s usually too late for inspection anyway. If you can, however, do try to get a sample of the mushroom to take to your vet to help with identification. Symptoms of mushroom poisoning include dehydration, weakness, vomiting, diarrhea, and even coma.4

4. Daffodils

Daffodils

These popular springtime flowers have become a seasonal staple. Unfortunately, daffodils are also very toxic plants for dogs and cats when they’re ingested. They can cause a range of symptoms — such as diarrhea, vomiting, abdominal pain, and even cardiac arrhythmias.5 They might be pretty, but that doesn’t mean they’re harmless.

5. Marijuana

Marijuana

Even a small amount of marijuana, aka cannabis, can be toxic to pets. The intoxicating component comes from tetrahydrocannabinol (THC), which is the psychoactive chemical within the plant that causes its mind-altering effects in humans. For animals, however, this chemical causes several detrimental effects — such as lethargy, altered blood pressure, low or fast heart rate, slowed breathing, coma, and seizures. Pets can be affected by ingesting baked foods containing marijuana, ingestion of the plant itself, and secondhand smoke.6

6. American Holly

American Holly

Also known as “winterberry,” this shrub features fruit that can be appetizing (but very toxic) for pets. The ingestion of this fruit can lead to outcomes like depression, vomiting, and diarrhea.8 These trees may be common, but fortunately, most animals are naturally deterred from eating their prickly leaves.

7. Lilies

Lilies

Lilies are extremely poisonous plants for cats that should be avoided at all costs. Whether it’s a day lily, tiger lily, peace lily, or one of the many other lily varieties, the ingestion of just one or two leaves could lead to potentially deadly kidney failure or other complications. Symptoms of lily poisoning to look out for include loss of appetite, vomiting, and drooling. Lilies are a pretty common house plant, and owners should be mindful about checking the lily leaves for signs of pet ingestion (chew marks, missing leaves, etc.).

8. Oleander

Oleander

This popular evergreen shrub is found in warm regions throughout the country. Unfortunately, virtually every part of it is also dangerous. Oleander contains naturally occurring cardiac toxins that can gravely affect the nervous systems of cats and dogs, leading to abnormal heart rhythms, nausea, vomiting, seizures, and tremors.10

9. Clematis

Clematis

Every bit of this woody vine is toxic to pets. The clematis can be found throughout the country and features thick vines with vibrantly colored flowers that range in color from pink to white to red. Once eaten, clematis can lead to vomiting and diarrhea.11 Steer clear of this plant, especially if your pet is known to eat plants.

10. Poison ivy

Poison Ivy

While generally not considered to be toxic, poison ivy can still pose a threat to our pets. Skin reddening, swelling, vomiting, diarrhea, and pesky itching can occur when cats or dogs make contact with this plant’s sap. Still, it’s not nearly as common in our furry counterparts as it is in us, and that’s in large part thanks to the extra protection provided by their fluffy coats.

11. Tulips

Tulips

Tulips are a common springtime sight throughout the U.S., where they pop up in a variety of bright colors. These cup-shaped flowers are one of the more common poisonous plants to cats and dogs, and the bulbs are an especially toxic part of the tulip. However, the entire plant is dangerous when eaten and can lead to symptoms like mouth/throat irritation, diarrhea, drooling, vomiting, and difficulty breathing.12
