Lily Toxicity in Cats

Westbury Animal Hospital - Tuesday, March 11, 2014

There are a lot of household items that owners forget can be a source of toxicity to our pets. Thigpen (named after the "Peanuts" character), has allowed us to use him as a case example this month for lily toxicity. 

There are many different types of lilies, and while beautiful to have in flower arrangements, many of them have different toxic effects on cats. See the different concerns below:

Lily of the Valley: Cardiac Arrhythmias

Calla LilyThese plants contain calcium oxalate needles throughout the plant. The irritation from these crystals result swelling of the gums and foaming the mouth. Luckily this is the least toxic of the lily family, but can still cause some pain.

Day Lily, Easter Lily, Tiger Lily: These lilies can cause acute renal failure and death. All parts of the plant are toxic, even the pollen. 

This is Thig, a very affectionate and loving cat who decided a day lily was his food item of choice. Thig was very fortunate that his owner discovered the eaten plants quickly and sought treatment for him right away. Thig stayed in the hospital for 2 days for a decontamination period to prevent any toxic effects and went home no worse for the wear. 

If your cat is suspected of ingesting lilies, it is recommended to seek veterinary care immediately for further recommendations.
