Easter Lilies and Cats
Easter lily poisoning in cats was recognized as a problem by the National Animal Poison Control Center. The scientific name for Easter lily is Lilium longiflorum. Since then, many other lilies in the Lilium genus have also been associated with toxicoses. Some of these include: Tiger lilies, Asiatic hybrid lilies, Japanese lilies, Red lilies, Rubrum lilies, Stargazer lilies, Western lilies, and Wood lilies.The Lilium genus contains approximately 100 potentially toxic species and innumerable hybrids. In addition to the Lilium genus, Day lilies of the Hemerocallis genus also cause similar problems.
All parts of the plant should be considered toxic. Recent research has shown that the flower is especially toxic. As little as a single bite of the plant may cause a problem. All suspected ingestions of any plant in the Lilium or Hemerocallis genera should be treated as possible toxicoses for cats. The toxin in lilies is unknown, so is the mechanism of action.
Signs of Poisoning
The onset time for the initial GI signs is usually within 3 hours of ingestion. These initial signs include vomiting, salivation, anorexia and depression. Increased urination and urine abnormalities are evident within 12-24 hours after toxic ingestions. Increased thirst has also been noted in some cases. Dehydration is usually noticed around 24 hours after ingestion. Subsequent problems include a reoccurrence of vomiting, lack of urination, weakness, low temperature and death within 3-7 days.
Pet owners should be aware of the potential for this life-threatening toxicosis during this time of the year. Many homes contain both cats and Easter lilies!
