What can I do to get the word out?

There are many things a concerned individual can do to decrease the number of lily poisonings in cats :

  1. Talk to your relatives, neighbors, co-workers and friends who have cats and tell them about the dangers of lilies. Refer them to this website. E-mail the link to this website to friends and family.
  2. When ordering flowers for delivery to homes with cats, specifically request that lilies not be included in the arrangement. Most on-line floral delivery services allow for “special requests” to be made. When the arrangement arrives, call the recipient and make sure that lilies have not been included.
  3. Do not bring lilies into your home. If you receive a floral arrangement with lilies in it, throw the lilies away or bring them to a location where there are no cats. Many cats have been poisoned by lilies that the family mistakenly thinks have been put “off limits” within the home.
  4. Remove daylilies from your yard or garden, if there are cats who wander outdoors.
  5. Talk to your local supermarket’s floral department manager and area florists and inform them of lily poisonings and cats.
  6. Ask your cat’s veterinarian to discuss lily toxicity with each cat client.
  7. Work with your local humane society to increase awareness of this problem.
  8. Talk with the person at your house of worship that handles decorations for the sanctuary and make sure that poisonous lilies are not given to members with cats.
  9. Talk with the local garden store manager and make them aware of the problem daylilies pose to cats.
  10. Know and share the toll-free number to the ASPCA’s Animal Poison Control Center : 1-888-426-4435. The Center is staffed 24/7 by a team of veterinarians and support personnel. There is a $65 consultation fee (payable by credit card) for the use of this service.
