Yucca, a kind of desert plant, are popular garden plants thriving in warm, dry areas. They don’t need a ton of water to grow, and they are distinctive and beautiful, with a big spray of spike-shaped leaves. They also do well as hardy houseplants indoors.

But if you have cats, make sure to keep their paws off—all parts of this plant are poisonous to cats.


Recognizing Yucca

Yucca plants are easy to recognize. They grow a cluster of bluish-green leaves that are long, triangular, and slightly sharp. They might have a short trunk or grow right next to the ground. From a distance, they often look like a ball of spikes. They grow well in hot, arid climates and during the Spring, it will have a long stalk with small white flowers.

Saponins and Pet Poisoning

Yucca plants are poisonous to cats because they are full of saponins. This compound is meant to keep unwanted animals and insects clear, and it generally does a pretty good job. It is spread throughout the plant, including in the leaves, which is where cats are most likely to nibble. However, the concentration is low enough that your cat is unlikely to face a serious case of poisoning.

Poisoning Signs and Treatment

If your cat does eat yucca, the most common symptom is vomiting or diarrhea. Vomiting helps your cat get rid of the toxin and usually if your cat vomits without any other symptoms, they won’t need extra medical care. However, in serious cases or if your cat eats small amounts over time, other symptoms might occur including drooling, weakness, lack of motor coordination, and in the most serious cases seizures. If you see signs of these more serious symptoms, seek vet care immediately. Yucca poisoning can be fatal in the worst cases.

Yucca vs Cassava

Sometimes, cassava plants, also called “yuca” are confused with yucca. Although these plants have similar names, they aren’t actually closely related. Cassava does contain toxic compounds, but they are at a much lower concentration than the saponins in yucca so they are generally considered to be safe for pets.

Yucca Extract

Yucca plants aren’t safe for pets to eat, but you might notice yucca products being marketed for cats or lurking in an ingredient list. Don’t worry—yucca extract is a rare but not dangerous ingredient if it’s been properly processed. The extraction process removes saponins so that your cat won’t be hurt. Most often, it’s part of herbal or alternative remedies for humans and cats, and although we can’t say that they have any research to support their health benefits, they do offer the benefit of not being poisoned.

Last Thoughts

Overall, you should probably avoid yucca plants if your cat tends to graze. Most cats won’t be tempted to nibble on yucca plants, especially if they have a pot of soft grass to chew on, but it is a risk to plant yucca somewhere that cats can access it. Yucca poisoning in cats is usually fairly mild, but if your cat ingests a large amount, either all at once or over several days, it may cause serious symptoms and require vet care.
