Easter grass and tinsel have been banned in our house for years anyway (I think it breeds at night, and I never can seem to get rid of it!).
I never knew about the lily toxicity. I have a beautiful Easter lily on my dining room table, which I'll have to move out of Susie's reach.

What part of the plant is considered toxic: All parts of the plant are considered toxic. Any exposure to the plant could be toxic to the cat, ingestion of part of a leaf or licking pollen that came into contact with their fur, could cause renal (kidney) failure.
Symptoms of lily toxicity: Cats will generally start to vomit within a few hours of exposure. The affected cat might seem lethargic and not want to eat. Many owner will not find this behavior odd for their cat and the symptoms will go untreated. Kidney failure will start to develop within 24 72 hours after eating the plant. Kidney failure symptoms include but are not limited too: increased thirst, increased urination, vomiting, lethargy, not eating, and dehydration.
Diagnosis: The veterinarian will want to do blood work to check the cats kidney function. The kidney's blood values will be elevated within 12 18 hours after eating the plant. Death can occur in 3 6 days after eating the plant. Many owners will not have seen their cat ingest the plant so the kidney failure will be a shock to the owner. Many older cats develop kidney failure with time but eating lilies brings on kidney failure quickly to both young and old cats, that is why it is so devastating.
Treatment: If the cat is treated within a few hours after eating the plant the outcome is pretty good. The veterinarian will probably induce vomiting and give activated charcoal to further absorb any toxin. The veterinarian will also want to set an IV catheter and administer fluids to combat dehydration and shock. If the cat does not receive treatment within 18 hours of ingesting the plant I'm afraid there is not a lot that can be done. A decision needs to be made by the owner and the veterinarian, trying to treat symptoms might give you more time with your cat but many times death or euthanasia because of severe kidney failure is the outcome.
