Just today, the FDA released a warning about Easter (and for that matter, Tiger, Asiatic, Day, and Japanese Show) lilies. The entire plant is poisonous to cats—even nibbling a leaf can cause acute kidney failure. The FDA alert also notes that even if your cat brushes against the lily flower and gets a few grains of pollen on her fur, and then licks it off, the results can be devastating. Symptoms of lily poisoning include vomiting and lethargy. If you suspect that your cat has lily poisoning, rush her to the vet for immediate treatment, advises the Pet Poison Helpline. Prompt treatment is essential to her recovery. More from Prevention: 5 Ways To Keep You Cat From Driving You Absolutely Crazy
