Cats and plants are common in households, but they don’t always mix well. Cats are curious animals that sometimes like to chew, lick, and eat things. While it is fine for cats to eat some house plants (at least in small amounts),  there are some that are known to be poisonous if ingested.

Unfortunately, the yucca plant is poisonous to cats. It contains steroidal saponins which are toxic to cats.1 Eating a yucca can lead to symptoms including vomiting, diarrhea, loss of coordination, and even convulsions. If your cat eats yucca and exhibits any of these symptoms, you should consult a veterinarian as soon as possible.

Read on for more information on yucca plants, their effects on cats, and for details of other house plants that are considered potentially dangerous to them.

Yucca Plants

In the wild, Yucca plants are native to Mexico and the Caribbean. They can withstand droughts, which is especially useful if you are a houseplant owner that tends to forget to water your plants. They are visually appealing, thanks to their long and pointy fronds, and they can grow quite large, although the yucca is a slow-growing plant that can take many years to mature.

The root of the yucca is used to make medicines and supplements. It has been used to treat osteoarthritis, migraines, inflammation, colitis, high cholesterol, and stomach disorders. Most of the yucca can be eaten or consumed. Humans can consume the stems, leaves, flowers, and the fruit of almost all types of yucca. Most of the time.

Yucca extract is used in some carbonated beverages; however, there’s not enough scientific data to back its medicinal claims. We do not endorse or recommend yucca for anything other than planting, growing, and admiring.

Yucca Toxicity In Cats

Although edible for humans, yucca plants are not considered safe for cats to consume. In fact, they are listed as toxic. The steroidal saponins are found throughout the plant, including in the root. But it is also in the leaves, stalks, and fruit. Although these are considered toxic, they are more likely to cause major problems if your cat regularly grazes on the plant, rather than if it tries one leaf. If they do try a mouthful of yucca, your cat may experience mild vomiting and diarrhea. If they  eat the plant regularly, your feline friend could endure severe vomiting and diarrhea as well as convulsions. Severe diarrhea is a problem because it causes serious dehydration. You should seek veterinary attention for your cat if it is vomiting regularly.

Other Potentially Harmful Houseplants

You should avoid having yucca plants in your home if your cat is prone to chewing plant leaves. And the yucca isn’t the only houseplant that can prove toxic to cats.

1. Lilies

The fact that lilies are toxic to cats is a well-known fact but bears repeating. They are highly toxic to cats. The leaves, the stem, and even the water in the vase can all prove very dangerous. If you have the kind of cat that likes to nibble everything, be very careful about having this plant in your home. Vomiting, diarrhea, and excessive drooling are the main symptoms of lily poisoning and typically start within 12 hours of ingestion.


2. Aloe Vera

Aloe vera is another plant that has long been revered for its medicinal properties in people. It is also popular for its unique look, but if your cat ingests the juice from aloe vera, it could become very sick. Loss of appetite and a change in urine colour may be followed by tremors.


3. Peonies

Peonies are not only beautiful little plants but, if they are given the right conditions, they can flower and flourish for hundreds of years. The same can’t be said for cats that eat them. Peonies are known to cause depression as well as vomiting and diarrhea when consumed by felines.


4. Eucalyptus

Yet another plant famed for its medicinal values, the eucalyptus is also another houseplant that can cause serious illness in cats. Any part of the plant can lead to an adverse reaction that includes symptoms like vomiting, diarrhea, and drooling. Like Peonies, it can also cause depression as well as weakness and listlessness.


5. Rubber Plant

There are lots of different genus of rubber plants, and they are all considered toxic to cats. Symptoms include vomiting, diarrhea, depression, and loss of coordination. Reactions to the rubber plant are not usually as severe as with other plants, but you should still speak with a veterinarian if you believe your cat has consumed any.

Top 3 Safe Replacements For Your Yucca

Not all houseplants are toxic to cats. If you’ve had to get rid of your rubber plants, yucca plants, and aloe vera, here are three alternatives to replace them.

1. Spider Plant

The spider plant is not dangerous to cats, although we can’t guarantee that cats aren’t dangerous to these hanging, trailing plants. They purify the air but dislike direct sunlight. They are also tough plants that will survive most things other than, perhaps, being eaten by your cat.


2. African Violet

The African violet is a dainty, pretty little flower. They do need regular watering but with regular fertilization, they will bloom throughout the year and bring a dash of pretty color to your home.


3. Money Tree

If you want a large plant to take the place of a yucca, the Money Tree is a good option, and it could help bring financial prosperity. This large plant is not toxic to cats but can cause some gastrointestinal upset if your feline friend eats it too often.

Conclusion

Some house plants are potentially toxic to cats. The yucca plant is one such plant. If you have a cat that likes to chew or eat things it shouldn’t, you should avoid keeping this type of plant at home. Other plants to avoid include Aloe Vera and Peonies, but you can replace these with African Violets, Spider Plants, and Money Trees. That way, you can still enjoy the many benefits of having plants indoors while ensuring your cat doesn’t get ill.
