Are Rattlesnake Plants Toxic to Cats?


Rattlesnake plants, scientifically known as Calathea lancifolia, are popular houseplants appreciated for their striking foliage. While these plants can add beauty and vibrancy to any indoor space, pet owners often raise concerns about their potential toxicity to cats. In this article, we will explore the relationship between rattlesnake plants and cats, examining scientific research and anecdotal evidence to determine whether these plants pose a threat to feline companions.

Scientific Research Findings

The scientific community has conducted several studies to investigate the toxicity of rattlesnake plants to cats. However, it is important to note that these studies have yielded varying results, making it difficult to draw definitive conclusions.

Case Studies and Anecdotal Evidence

While scientific research provides valuable insights, anecdotal evidence and case studies are also significant in understanding the potential effects of rattlesnake plants on cats. Pet owners’ experiences can shed light on any possible toxicity concerns.

Based on anecdotal evidence, some cat owners claim that their feline companions have shown symptoms of illness after interacting with rattlesnake plants. These symptoms may include vomiting, diarrhea, lethargy, or decreased appetite. However, it is essential to approach anecdotal evidence with caution, as individual experiences can vary, and other factors may contribute to the observed symptoms.

Common Toxic Compounds

To better understand the potential toxicity of rattlesnake plants, it is crucial to examine the common compounds found within them.

  • Calcium Oxalate Crystals: Like many other plants, rattlesnake plants contain calcium oxalate crystals. When ingested, these crystals can irritate the mouth, tongue, and throat, leading to discomfort and potential drooling in cats.
  • Alkaloids: Some plants, including rattlesnake plants, contain alkaloids that can be toxic to animals. These compounds can lead to gastrointestinal upset if consumed in large quantities.

Preventive Measures

While the exact level of toxicity of rattlesnake plants to cats remains uncertain, it is always advisable to take preventive measures to ensure the safety of our beloved pets. Here are some guidelines:

  • Placement: Keep the rattlesnake plants out of your cat’s reach by placing them in high or inaccessible areas.
  • Supervision: Supervise your cat’s interactions with plants to prevent accidental ingestion.
  • Alternative Plants: Consider selecting pet-safe houseplants as an alternative to rattlesnake plants.


While scientific research has not provided definitive evidence on the toxicity of rattlesnake plants to cats, anecdotal evidence suggests that some feline companions may exhibit adverse reactions after exposure. Considering the presence of calcium oxalate crystals and potential alkaloids, it is prudent for pet owners to exercise caution and take preventive measures to ensure the well-being of their cats. If you suspect that your cat has ingested any plant or is displaying unusual symptoms, it is advisable to consult a veterinarian for proper diagnosis and guidance.
