Rhubarb, a common garden plant, poses a significant health risk to cats. While humans typically consume the stalks, cats can be attracted to any part of the plant, including the highly toxic leaves. Ingestion can lead to poisoning and adverse health effects. Cat owners should understand the dangers and what steps to take if exposure occurs.
Why Rhubarb is Dangerous for Cats
Rhubarb contains compounds harmful to cats, primarily soluble calcium oxalates and oxalic acid. These substances are present throughout the plant, though they are more concentrated in the leaves. When consumed, oxalates are absorbed from the gastrointestinal tract into the bloodstream.
In the bloodstream, soluble oxalates bind with the body’s calcium, rapidly decreasing calcium levels, a condition known as hypocalcemia. This calcium depletion disrupts normal bodily functions. Oxalate crystals can also irritate the digestive system and crystallize within the kidneys, causing damage and potentially leading to kidney failure.
Symptoms of Rhubarb Poisoning in Cats
Cats that have ingested rhubarb may display various symptoms, ranging from mild to severe depending on the amount consumed. Early signs often include increased salivation, vomiting, and diarrhea. A cat might also show a decreased appetite and experience abdominal pain, indicated by restlessness.
More severe symptoms can manifest due to drops in calcium levels and kidney damage. These include lethargy, weakness, muscle twitching, tremors, and a general lack of coordination. Affected cats may also exhibit changes in thirst and urination patterns or even develop seizures. Symptoms can appear relatively quickly.
Immediate Actions After Ingestion
If a cat is suspected of eating rhubarb, immediate action is necessary. First, remove any remaining plant material from the cat’s reach to prevent further ingestion. Then, contact a veterinarian or a pet poison control center without delay. Early intervention significantly improves the chances of a positive outcome.
When contacting a professional, provide details such as the amount consumed, the plant part involved (leaves or stalk), and any current symptoms. Do not induce vomiting unless specifically instructed by a veterinary professional. Veterinary guidance is crucial for determining the appropriate course of action, which may involve supportive care like intravenous fluid therapy.
Long-Term Health Implications and Prevention
While timely veterinary care can lead to recovery, severe rhubarb poisoning can sometimes result in lasting health issues, particularly chronic kidney disease due to oxalate damage. Prolonged loss of appetite can also lead to significant weight loss if not addressed. Preventing exposure is the most effective approach to safeguarding a cat’s health.
To prevent cats from accessing rhubarb, consider its placement in gardens. Fencing off rhubarb plants or growing them in areas inaccessible to pets can be effective. Regularly inspecting outdoor spaces and removing any wild rhubarb also helps reduce risk. Opting for cat-safe plants like cat grass or catnip provides safer alternatives for their natural curiosity.
