Is Lily of the Valley Toxic To Cats? 

Absolutely. Lily of the Valley is toxic to cats.

This article is written in collaboration with a team of experienced DVMs (doctors of veterinary medicine). With their insights, we strive to provide accurate and up-to-date information on the potential risks associated with various plants and their effects on our feline friends. We have also cross-referenced our findings with high-authority websites such as ASPCA and PetMD to ensure comprehensive and reliable information.

Popular for its pure white blooms, the Lily of the Valley is not only an attractive perennial plant but also a potential danger to cats. The plant contains cardenolides, which are cardiac glycosides that can disrupt a cat’s gastrointestinal systems and adversely affect the functioning of their hearts. It is essential to note that all parts of the Lily of the Valley, including the roots, stems, leaves, blooms, and berries, are toxic. The bulb, in particular, has a higher concentration of cardiac glycosides. Additionally, the plant contains saponins that can lead to symptoms like nausea, diarrhea, blood in the stool, and stomach pain in cats.

  8. Dilated pupils: A reaction to the plant’s neurotoxic effects.

First Aid and Treatment of Lily of the Valley Poisoning in Cats

Inducing emesis or delivering treatment to make your pet vomit is not recommended with this plant poisoning because it is absorbed so quickly. Your veterinarian, on the other hand, may do gastric lavage, which involves washing out the stomach while under general anesthetic. To absorb any leftover poisons, activated charcoal can be used orally.

Other treatments may be also provided by the vet such as intravenous fluid therapy to rehydrate your cat and giving medications to your cat such as gastro protectants, anti-nausea, and anti-arrhythmic, among others. Medications prescribed will still depend on your cat’s symptoms and the severity of the condition.
