Is Snake Plant Toxic to Cats?

The Snake Plant

Among the most popular houseplants, the snake plant is known by many names - mother-in-law's tongue, Sansevieria, or viper's bowstring hemp. Originally from West Africa, the snake plant stands out for its long sword-like leaves, which grow upright and can reach up to several feet in height. The snake plant is a hardy plant beloved by many homeowners for its ability to purify the air, making it a popular choice for indoor spaces. It is also low-maintenance, making it the perfect addition to offices and homes alike. However, concerns about the snake plant's toxicity to pets, particularly cats, have been raised. There is some conflicting information on whether the snake plant is indeed toxic to cats, and this article aims to shed some light on the matter.

Snake Plant Toxicity

When it comes to the toxicity of the snake plant, most information at hand is anecdotal, with no official scientific studies on the matter. This lack of scientific research complicates the matter, leading to much debate on whether the snake plant is indeed toxic to cats. Snake plants contain saponins, a type of chemical compound, which give the plant its foamy texture when crushed. However, these compounds are known to be toxic to both dogs and cats and can cause symptoms such as nausea, vomiting, and diarrhea. In addition, snake plants contain calcium oxalate, a type of compound that can cause oral irritation and swelling of the tongue and throat when ingested. According to some sources, snake plants are considered mildly toxic to cats. While consuming a small amount of the plant is not likely to cause severe symptoms, ingestion of larger quantities can lead to an emergency situation.

Symptoms of Snake Plant Toxicity in Cats

Signs and symptoms of snake plant toxicity in cats can range from mild to severe depending on the amount ingested. Symptoms can include:
  • Vomiting
  • Diarrhea
  • Excessive drooling
  • Swelling of the mouth, tongue, or throat
  • Nausea
  • Lethargy
  • Difficulty breathing
  • Irregular heartbeat
If you suspect that your cat has ingested a snake plant, it is important to seek veterinary care immediately, especially if your cat displays any of the more severe symptoms mentioned above.

Preventing Snake Plant Toxicity in Cats

As cat owners, it is important to take the necessary steps to prevent snake plant toxicity from occurring in our homes. Here are some tips to keep your cat away from snake plants:
  • Place snake plants out of reach of cats.
  • Spritz bitter apple spray on the leaves of the snake plant to deter cats from chewing on them.
  • Train your cat to avoid the snake plant using positive reinforcement, such as treats and praise.
  • Opt for pet-friendly houseplants such as spider plants, areca palms, and African violets that are known to be safe for pets.

Conclusion

It is clear that taking the necessary steps to prevent snake plant toxicity in cats is crucial to keeping your beloved feline friend safe. While scientific research on this topic is lacking, it is important to keep in mind that snake plants are mildly toxic to cats, and ingestion of large amounts can be harmful and even life-threatening. In conclusion, as much as we love our houseplants, we must prioritize our pet's safety and take the necessary precautions to ensure that they are not exposed to toxic plants such as the snake plant. Opt for pet-friendly plants and always consult your veterinarian if you suspect that your cat has ingested a toxic plant. Remember, prevention is always better than cure.
