Why is the ZZ Plant Toxic for Cats?

ZZ plant is an aroid plant, and like most aroids, it contains small and sharp crystals known as Calcium Oxalate crystals.

This crystal’s function is to regulate the Calcium flow in the plants and maintain plant tissue rigidity.

However, this crystal has evolved and started to function as a defense mechanism against grazing animals.

The needles and barbs of these Calcium Oxalate crystals are responsible for injecting toxins into the blood of the animals.

When your cat chews on the plant parts, the calcium oxalate crystals penetrate the mouth’s tissues.

It embeds itself on the cats’ tongue, throat, and stomach, causing irritation and immediate discomfort.

These irritating crystals not only cause illness but can also result in the death of the cat.

Which Part and What Amount of ZZ Plant is Toxic to Cats? 

You can find toxic Calcium Oxalate crystals in almost all parts of the ZZ Plant.

Any part of the ZZ plant structure that has its sap is toxic to cats.

Normal contact won’t do any harm, but if the sap gets on the eyes or skin, or if the leaves are ingested, the cats can start showing being poisoned.

Although all the ZZ plants are toxic to cats, even a small amount of toxin exposure can cause poisoning symptoms.

But it also depends on how the cat got exposed to the toxins. Whether the cat ingested it, only nibbled it, or got the sap in its skin and eyes.

If only the skin were exposed to the toxins, the cat would start scratching and pawing itself.
