ASPCA National Animal Poison Control Center Warns Cat Owners of Lily
Dangers.

As spring approaches, lilies will become more common in households as potted
plants or in bouquets. According to Michigan State University Extension's
Grower Guide, Easter lilies are the third most important flowering pot-plant
grown in the United States, with l0 to 11 million plants produced annually.
Unfortunately, several types of lilies can be deadly to cats. Easter lily,
tiger lily, rubrum, Japanese show lily, some species of day lily, and
certain other members of the Liliaceae family can cause kidney failure in
cats.

Within only a few hours of ingestion of the plant material, the cat may
vomit, become lethargic, or develop a lack of appetite. These signs continue
and worsen as kidney damage progresses. Without prompt and proper treatment
by a veterinarian, the cat will develop kidney failure in approximately
36-72 hours.

All parts of these lilies are considered toxic to cats and consuming even
small amounts can cause severe poisoning. If there is a lily in your home,
there is always the chance that your cat could be accidentally exposed. For
this reason, cat owners should avoid exposing their cats to plants of the
Liliaceae and Hemerocallis family.
