Lily Toxicity

LILY FLOWER TOXICITY IN CATS

Lilies (of the genera Lilium and Hemerocallis) are commonly used in many flower arrangements as they are a beautiful decorative flower.  However did you know that these are extremely toxic to cats? Lilies can cause kidney (renal) failure and can be fatal in cats.

 

What is the toxic substance in Lilies?

The toxic substance in lilies has not been identified but all parts of the plant (flowers, leaves, stem & roots) are toxic to cats.  The toxic dose is also unknown but is thought that toxicity occurs from ingestion of, or mouthing very small amounts of the plant material. 

Many indoor cats and especially playful kittens may be intrigued by a flower arrangement, in an environment that is otherwise void of vegetation. While investigating the flowers, cats may chew and eat the plant.  Even if a cat rubs up against the lilies and has pollen on its fur, it is cause for alarm.  Cats are fastidious groomers and ingesting this pollen can be fatal. Outdoor cats are also susceptible if these plants are in your garden.  It is important to note that only a small amount chewed when playing can kill a cat.

 

Why are cats susceptible to this type of toxicity?

Cats seem to be unique domestic pets in their susceptibility to certain toxins, possibly due to their different metabolism.

 

What are the symptoms?

When cats ingest some of the lily the first signs will occur very quickly within 2-12 hours.

The effect cat may be:

• Lethargic
• Vomiting
• Sickness

A mild improvement may be seen after this, but not for long.

Acute renal failure may occur within 24-72 hours, at which time your cat will be critically ill.

Without treatment, cats will become progressively ill and die within 3-7 days.

 

Symptoms of acute kidney failure

• Lethargy
• Disinterest in food/loss of appetite
• Vomiting
• Diarrhoea
• Minimal water intake
• No urination.

 

How is Lily toxicity diagnosed?

Diagnosis is difficult as there is no specific test that can identify lily intoxication with certainty.

Diagnosis may include:

• Blood & Urine Tests
• Ultrasound
• Biopsy of Kidneys

 

Treatment

There is no specific treatment for lily toxicity but aggressive fluid therapy is usually given to flush out the kidneys.

The key to success in these cases is early recognition and aggressive management of the ensuing kidney failure.  However even in the hands of the best veterinarian, a successful outcome is not assured.  For that reason PREVENTION is much better than attempted cure.

It is recommended that cat owners remove lilies from areas that cats have access to and consider alternative plants such as orchids, cactus or daisies.

 

What do I do if I suspect my cat has ingested or chewed on lilies?

 Seek veterinary treatment immediately for your cat.
