10 Poisonous Plants for Pets

While there are many species of flowers and plants that are appealing to our human eyes, several are also toxic to our four-legged friends. Here are 10 of the common plants that are poisonous to our pets.

1) Autumn Crocus

This plant is poisonous to both cats and dogs and can cause vomiting, seizures, kidney damage and more.

While these 10 plants are common culprits to pet poisoning, there are hundreds of more plants that can trigger similar symptoms. Check out these detailed lists from the ASCPA and remember to double check before adding any new plants to your garden.

2) Azalea

Toxic to cats and dogs, these plants’ toxins are very potent.  The ingestion of a few leaves may be enough to induce vomiting, diarrhea, or even coma and death in both canines and felines.

3) Daffodil

The entire plant may be poisonous to both cats and dogs, but the bulbs of these plants are particularly high in toxicity.  Eating any part of the daffodil may induce vomiting, diarrhea, drops in blood pressure, and even heart arrhythmias.

4) Dumb Cane (Dieffenbachia)

The entire “Dumb Cane” family of plants is toxic to cats and dogs.  It will cause irritation and swelling in the pet’s mouth, making it difficult for them to swallow and triggering a burning sensation.

5) Tulip

Tulips are capable of causing nausea, excessive drooling, and difficulty breathing in both cats and dogs.  The bulbs, like in daffodils, are the most toxic part of the plant.

6) Kalanchoe

Commonly called the “Mother In Law” plant, these beautiful flowers can induce vomiting, drooling, weakness, cardiac arrhythmia, seizures, and more in cats and dogs.

7) Sago Palm

This plant is highly toxic to both cats and dogs and causes bloody vomiting and diarrhea, liver failure, jaundice, and bleeding disorders when ingested.

8) Oleander

This outdoor shrub is dangerous for several animal species-including cats, dogs, birds, cows, and horses.  This plant can cause drooling, vomiting, bloody diarrhea, muscle tremors and incoordination, and fatal heart problems.

9) Lilies

This plant more toxic to cats than dogs, but it can still be deadly.  Symptoms to watch out for include lack of appetite, vomiting, diarrhea, lethargy, dehydration (often seen as inappropriate urination or extreme thirst), and seizures.

10) Amaryllis

Highly poisonous to cats and dogs, this plant causes excessive drooling, vomiting, lack of appetite, difficulty breathing, and abdominal pain.
