Yes, snake plants are toxic to cats, due to a compound called saponin that is dangerous for cats’ digestive systems.

Are snake plants dangerous to cats?

Snake plants (Dracaena trifasciata), also called “Mother-in-Law’s Tongue,” are popular plants because of their ability to thrive despite being cared for by even the most novice plant parent. Snake plants contain saponins, compounds that contribute to their hardiness. Saponins help protect snake plants from insects, fungi, and bacteria. But when ingested, saponins can cause gastrointestinal upset in cats.

Cholesterol is important for cell membrane stability throughout the body, including the intestines. When a cat ingests a plant with saponins, the saponins will bind to cholesterol, weakening intestinal cells. This can lead to water imbalance and result in diarrhea. In severe cases, hemolysis (destruction of red blood cells) can occur. 

What should I do if my cat has eaten a snake plant?

If you catch your cat in the act or find little nibble marks in your snake plant, watch closely for gastrointestinal signs. The toxicity of snake plants is relatively low, so if your cat only took a tiny taste they may only experience a short bout of diarrhea with no other symptoms.

How to Deal with Cat Diarrhea

Dr. Audrey K. Cook’s tips to getting to the bottom of a sh*tty situation.

Have your cat seen by a veterinarian if they develop severe (or bloody) vomiting or diarrhea, weakness, or lethargy. If your cat doesn’t have any symptoms but you’re worried about the amount of snake plant ingested, you can also contact an animal poison control center (ASPCA Animal Poison Control or Pet Poison Helpline).

Diagnosing snake plant poisoning in cats

Vomiting and diarrhea are non-specific symptoms, meaning there are a myriad of possible causes. If your cat has access to a snake plant, or you find your snake plant disturbed, inform your veterinary staff so they can put it on the list of possible causes for your cat’s symptoms. 

Symptoms of snake plant poisoning in cats

Treatment for snake plant poisoning in cats

Some cats can eat a small piece of snake plant without developing any issues. Cats that have symptoms after eating snake plant are treated symptomatically. This may include fluid therapy and medications for vomiting and diarrhea. If symptoms seem severe, bloodwork or other diagnostics may be recommended. Cats that develop profuse vomiting and/or diarrhea may require hospitalization.

How to prevent snake plant poisoning

The most effective way to prevent snake plant poisoning in cats is to make sure your cat does not have access to the plant. If there’s already a snake plant in your home, this may be easier said than done. Some curious cats will easily conquer any obstacles put in their way. If this is the case with your cat, find a new home for your snake plant and get a cat-safe replacement. 

Are all parts of snake plants poisonous to cats?

All plants of a snake plant are toxic to cats. Saponins, the toxic component, are most concentrated in the leaves. 

How do I stop my cat from eating snake plants?

The best way to stop your cat from eating a snake plant is to keep snake plants out of your cat’s environment. Some cats can be trained to stay away from certain items. The saponins in snake plants tend to make them bitter and would hopefully prevent your cat from eating too much (or any) plant material. But cats are weirdos, so don’t depend on the bitterness to keep them away. Just get rid of the plant. 

The bottom line: Are snake plants poisonous to my cat?

Snake plants are poisonous to cats, so when choosing houseplants, cat parents should opt for cat-safe options. There are plenty of online resources like ASPCA Animal Poison Control’s toxic and non-toxic plant list to help you make the right choice.

Other plants that are safe for cats

Rattlesnake plant (Goeppertia insignis): This tropical plant is both cat-safe and gives the same lush look as snake plants. 

Blushing bromeliad (Neoregelia carolinae): These plants have scarlet blooms and are perfect for adding a pop of color to your home.

African violet (Saintpaulia ionantha): African violets produce vibrant violet flowers that are safe for cats if they happen to nibble on them.

Other plants that are dangerous for cats

Easter lily (Lilium wallichianum): True lilies (including tiger lily, Daylily, star lily, Japanese show lily, and others) are extremely toxic to cats. Cats that eat lilies are at risk of developing gastrointestinal signs within three hours of ingestion and acute kidney failure within three days. In some cases, lily ingestion can be fatal to cats. 

Oleander (Nerium oleander): All parts of oleander plants are toxic to cats. Oleanders contain cardiac glycosides, which are compounds that can cause vomiting, electrolyte imbalances, cardiac arrhythmias, tremors, seizures, and death. 

Poinsettias (Euphorbia pulcherrima): Poinsettias are ubiquitous during the winter holiday season, but they should be kept away from your cat. These plants contain irritating sap that can cause drooling, vomiting, and diarrhea when ingested. Though uncommon, it can also cause irritation when it makes contact with skin and eyes.
