Famously known as the ZZ plant, the Zamioculcas Zamiifolia is a popular houseplant due to its ability to thrive even in unfavorable conditions. These hardy plants grow to about 3 feet tall indoors and have bright-green glossy leaves that some people think resemble feathers. The plant is typically fuller at the base and tapers off at the top. People love growing ZZ plants in their homes because they don’t have to be watered often, they can handle both indirect lighting and full sunlight while growing, and they’re hard for kids to destroy.

However, before deciding whether to bring one of these beautiful plants into your own home, you should know that ZZ plants are toxic to cats and dogs. Let’s take a look at how and why ZZ plants are toxic to cats and the safe alternatives out there.

Why Are ZZ Plants Toxic to Cats?

The ZZ plant is part of the Araceae family. Unfortunately, all the plants belonging to this family contain a compound called calcium oxalate. This compound is toxic to cats, dogs, and even humans. It’s made up of the same materials that cause kidney stones in humans.

This compound is insoluble, so the body cannot absorb it or easily pass it through the body. Calcium oxalate is needle-sharp, which is why the compound causes damage to cells and organs within the body. Luckily, cats don’t typically eat the ZZ plant or other plants within the same family, so internal damage is incredibly rare.

How Toxic Are ZZ Plants to Cats?

Fortunately, exposure to a ZZ plant is typically not lethal to cats. However, simply rubbing up against the plant or chewing on a leaf can cause unpleasant side effects, such as drooling, vomiting, a loss of appetite, and pawing at the mouth. These symptoms are temporary but can be alarming as they develop. If your cat gets a hold of a ZZ plant and shows signs of intoxication, contact your veterinarian for guidance and recommendations for treatment. Allow your kitty to rest, and encourage them to drink water until the symptoms subside. Offering a little milk or yogurt can help bind the crystals.
