Rhubarb ( Rheum rhabarbarum) is a popular perennial vegetable known for its tart, edible stalks often used in pies and desserts. However, this seemingly harmless plant poses a severe and potentially fatal toxic threat to cats.

Rhubarb plants are commonly found in gardens and can also be grown as ornamental plants in flower beds.

Rhubarb’s Toxicity Level

(Level 5) - Extremely Toxic

If poisoning symptoms appear, make sure to visit your vet right away, or call the APCC 24-Hour Emergency Poison Hotline for further assistance.

  • Level 1 - Minimally Toxic

    Ingestion may cause mild gastrointestinal upset, but is generally not life-threatening.

  • Level 2 - Mildly Toxic

    Ingestion can result in mild symptoms like vomiting, diarrhea, or drooling. Rarely fatal but may require veterinary care.

  • Level 3 - Moderately Toxic

    Eating these plants can lead to more pronounced symptoms like abdominal pain, lethargy, or difficulty breathing. Veterinary intervention may be necessary.

  • Level 4 - Highly Toxic

    Ingesting even small amounts can cause severe symptoms like organ damage, seizures, or cardiac failure without rapid treatment.

  • Level 5 - Extremely Toxic

    All parts of these plants are extremely poisonous to cats and can quickly lead to death, even with immediate veterinary care.

** Please note: Please note that toxicity level can vary based on the amount ingested and the specific cat. It's always best to keep these plants completely inaccessible to cats and seek immediate veterinary care or call the poison hotline if you suspect your cat has ingested any part of a toxic plant.

Observable symptoms your cat could have

Ingesting any part of the rhubarb plant, especially the leaves, can cause severe symptoms in cats. The leaves contain high concentrations of oxalic acid and soluble oxalate crystals, which are the primary toxic compounds. Symptoms may include:

  • Drooling and vomiting
  • Diarrhea
  • Lethargy and weakness
  • Tremors and seizures
  • Abdominal pain
  • Decreased appetite
  • Increased thirst and urination
  • Blood in urine
  • Kidney failure

Potential diagnosis your Vet may give

If you suspect your cat has ingested rhubarb, seek immediate veterinary care. Your veterinarian will likely perform the following steps to diagnose rhubarb toxicity:

  1. Physical examination: Your vet will check your cat’s vital signs and look for signs of distress or pain.
  2. Blood tests: These tests will help assess your cat’s kidney function and electrolyte levels, as rhubarb toxicity can cause hypocalcemia (low blood calcium).
  3. Urinalysis: This test can reveal the presence of oxalate crystals in the urine, indicating rhubarb ingestion.
  4. Imaging: X-rays or ultrasound may be performed to check for kidney damage or obstruction caused by oxalate crystals.

Your veterinarian may diagnose your cat with oxalate poisoningacute kidney injury, or renal failure depending on the severity of the toxicity and the extent of the damage.

Q: What animals cannot eat rhubarb?

The Story Behind the Rhubarb Plant

Rhubarb has a long and fascinating history dating back over 5,000 years. Native to the cold regions of Siberia and Mongolia, rhubarb was initially used for medicinal purposes in ancient China. It was traded along the Silk Road and eventually reached Europe in the 14th century.

In the 18th century, rhubarb gained popularity as a culinary plant in Europe and North America. The edible stalks were used to make pies, jams, and other desserts, earning rhubarb the nickname “pie plant.” However, the leaves of the plant remained largely unused due to their toxic properties.

Today, rhubarb is widely cultivated for its edible stalks and is a popular ingredient in many dishes. Despite its culinary uses, it is crucial to remember that all parts of the plant, especially the leaves, are toxic to cats and other animals.
