As far as plants
go, lilies are among the most beautiful, but this week at Broad Lane Vets we
nearly saw them lead to tragedy. They smell lovely and seem to last forever,
making them a fantastic addition to any floral arrangement. Many people adore
them, and most animals aren’t bothered by them, but for cats, lilies are
positively deadly. And it doesn’t take much. A single bite of leaf or lick of
pollen can be all it takes to send cats into irreversible kidney failure. This
was the case this week with 2 kittens that ‘broke into’ a closed room and took
a lick of the lily pollen. Fortunately their owner was ‘lily aware’, and headed
straight to the surgery with 2 kittens coated in pollen around their mouths and
noses.
Why are
lilies so toxic to cats?
• We don’t know
exactly which chemical within the lily is so dangerous, but we do know that
ingesting the smallest amount of leaf, stem, flower or even pollen can be
deadly.
• Other animals, including dogs and rabbits, can eat lilies with just a bit of
mild stomach upset and do not seem to suffer from toxicity.
What are the
symptoms of lily poisoning?
• At first, lily
poisoning can mimic other cases of eating something that they shouldn’t have,
so it can be difficult to know what has happened unless you saw them eat it.
Signs include vomiting and lethargy, lack of appetite and shaking.
• These initial symptoms can actually disappear for a few hours to a few days,
after the plant has passed through the digestive tract but before the real damage
becomes obvious.
• Within a few days, however, the symptoms become those of kidney failure. This
includes increased thirst and urination, dehydration, and worsening lethargy,
vomiting and loss of appetite. Eventually, this increased urination turns into
a decrease in urination, and finally no urination at all, which indicates that
the kidneys are no longer functioning.
What can be
done about it?
• If you think
your cat has eaten any amount of any part of a lily, it is critical that you bring
them to the vets right away, even before clinical signs appear. Remember you
can get advice and see a vet 24 hours a day by calling us on 02476 464789.
• If you bring them in within a few hours of ingestion, we are will likely to
induce vomiting and possibly give a substance called activated charcoal, which
will help lessen the effects of the toxins.
• Then, or if too much time has already gone by, we may put your cat on a drip
and give IV fluids for as long as necessary. These fluids will help support the
kidneys as they try to process the poison and flush out any toxins that do make
it into the blood stream.
• There is no special blood test to diagnose lily toxicity, so many cases go
undiagnosed. We will however likely run a general blood and urine test to check
how badly the kidneys may have been damaged. These tests will probably need to
be repeated several times during their stay in hospital.
What happens
next?
• If you are
able to get your cat to us within a few hours of ingestion, the chances are
much greater that they will make it through the incident with the appropriate
medical care. It is vitally important that your cat see us as soon as possible
to begin treatment.
• If no treatment is given, or the kidneys have been damaged to the point where
urination is starting to decrease, then sadly the chance of survival is very
low.
How can
lily poisoning be prevented?
• The best way to prevent lily
poisoning in your own home is to prevent lilies from entering your home in the
first place. This is easier said than done when well-meaning friends and family
bring you a lovely bouquet.
• Remember, however, that it’s
not just lilies in your house that can be deadly, always check your own garden
for these and other toxic plants.
• Spread the
word – by telling other people about the dangers of lilies, you are helping to
increase awareness of the problem. The ISFM (International Society of Feline Medicine) has launched a campaign
to help educate the public about lily toxicity. Their website has informative
posters and tags to be put around floral arrangements that contain lilies at
the florist. The more people know about lily toxicity, the safer all of our
cats will be.
