It’s every pet owner’s nightmare: one minute your dog or cat is sniffing around the house or on a walk, and the next you realize they’ve taken a bite out of a plant—possibly a toxic one. Pets are naturally curious, often using their mouths to explore the world. Unfortunately, many common household and garden plants can pose serious health risks to them.

At Mission Veterinary Clinic in Granada Hills, CA, we know how scary these moments can be. This guide will help you identify potentially toxic plants, recognize symptoms of poisoning, and take fast, effective steps to protect your pet’s health.

Why Some Plants Are Dangerous to Pets

Not all greenery is safe. Pets process certain compounds differently than humans, which can make even small amounts of a toxic plant harmful or even deadly. Common plant toxins include:

  • Alkaloids and glycosides – Can affect heart, liver, or kidney function.
  • Calcium oxalates – Cause painful mouth and throat irritation.
  • Essential oils and resins – Toxic if ingested or absorbed through the skin.

Common Toxic Plants and Their Effects

Highly Toxic Plants

  • Lilies – Especially dangerous to cats. Even licking a petal or grooming pollen off their fur can lead to acute kidney failure.
  • Sago Palm – Contains cycasin, which can lead to severe liver failure in both dogs and cats.
  • Foxglove, Oleander, Azaleas – Can affect heart rhythm and cause collapse, tremors, or seizures.

Moderately Toxic Plants

  • Pothos (Devil’s Ivy) – Causes drooling, mouth irritation, and difficulty swallowing.
  • Aloe Vera – Healing for humans, but can trigger vomiting and diarrhea in pets.
  • Tulips and Daffodils – Bulbs are particularly toxic, causing stomach upset and drooling.

Symptoms of Plant Poisoning in Pets

Early recognition is critical. Watch for:

  • Gastrointestinal symptoms: Vomiting, diarrhea, drooling, refusal to eat
  • Neurological symptoms: Lethargy, tremors, seizures, disorientation
  • Organ-specific symptoms: Jaundice, increased thirst or urination, abdominal pain

If you notice any of these signs, contact your vet or poison control immediately.

What to Do If Your Pet Eats a Toxic Plant

1. Remove the Plant

Take away any remaining plant material—both from your pet’s mouth and their environment. Look for evidence of chewing.

2. Monitor for Symptoms

Keep a close eye on your pet, especially for changes in energy level, appetite, or behavior.

3. Call for Help

Do not induce vomiting unless your vet specifically advises it. Instead, contact:

4. Head to the Vet

Bring a sample or a photo of the plant, if possible. At the clinic, your pet may receive:

  • IV fluids to flush out toxins
  • Anti-nausea medication or activated charcoal
  • Bloodwork to assess organ function

Preventing Plant Poisoning at Home

Opt for Pet-Safe Plants

Some attractive, non-toxic alternatives include:

  • Spider Plant
  • Boston Fern
  • Areca Palm

Consider providing cat grass or catnip for safe chewing.

Keep Toxic Plants Out of Reach

Use high shelves or hanging baskets. In homes with especially curious pets, it may be best to avoid toxic plants altogether.

Be Mindful Outdoors

Regularly inspect your yard and garden, especially if your pet roams freely. Keep an eye out for weeds or seasonal plants that may pop up unexpectedly.
