Top 10 Most Poisonous Plants for Cats

Poisonous Plants for Cats

Being surrounded by plants is beneficial to you and your cat’s health. In fact, cats and other animals are known to eat plants when they feel like they’re not getting enough fiber from their diet.

Aside from making your surroundings pretty, plants also absorb carbon dioxide and give out oxygen.

However, some seemingly pretty and harmless plants are poisonous to cats. And considering that cats are instinctively curious creatures, they sometimes fall victim to poisonous plants and suffer from toxicity.

If you have a cat at home, make sure to avoid bringing home the following plants:

1. Autumn Crocus

This flower can cause mild to severe toxicity in cats. If ingested, it could cause gastrointestinal problems such as drooling, abdominal pain, vomiting, and diarrhea.

All parts of this plant are highly toxic, but most of the toxins can be found in its bulbs, flowers, and seeds. Severe toxicity can lead to organ damage, heart arrhythmias, respiratory failure, seizures, and worst, death.

2. Azaleas and Rhododendrons

This beautiful garden shrub is another poisonous plant for cats. The level of its toxicity depends on the amount ingested.

If only tiny amounts were consumed, cats could display mild symptoms such as lack of appetite, diarrhea, vomiting, and abdominal pain. If eaten in large amounts, cats could experience low blood pressure or hypotension, abnormal heart rate, seizures, coma, and even death.

7. Lily

Lilies are the most poisonous plant to a cat. There are many kinds of lilies, but the most notorious of them is the Easter Lily.

Ingesting even tiny amounts of its leaves or pollen can cause acute kidney failure. Symptoms include vomiting, lack of appetite, lethargy, difficulty in urinating, and dehydration.

There is no antidote for lily poisoning, but vets usually give activated charcoal and IV fluids to combat the poison.

8. Oleander

Oleanders are known to be toxic not only in cats but also in humans and other animals.

The toxins found in oleanders affect mainly the heart, causing it to beat rapidly. Symptoms include nausea, drooling, heart arrhythmia, and seizures. 

9. Sago Palm

Found mainly in tropical areas, Sago palms are also one of the most poisonous plants for cats.

The survival rate is only 50% even when caught and treated early. The most poisonous part is found in its seeds which can cause acute liver failure.

10. Tulip

The whole tulip is considered toxic but the bulb contains the most toxins.

Although tulips only cause mild to moderate toxicity, it can still cause discomfort and irritation inside and around the mouth, as well as drooling and nausea.

In rare and severe cases, heart arrhythmias and swelling of the airways may occur.

Sadly, many cats have died due to plant poisoning. The key to avoiding this situation is by familiarizing yourself with these plants and never taking a chance.

If you are unsure of the plants you currently have, do a research. If your cat is showing signs of poisoning or toxicity, this is a medical emergency.

Bring your cat to the vet immediately so that the right antidote can be administered.
