Is Hawthorn Toxic to Cats?

What is Hawthorn?

Hawthorn, also known as Crataegus, is a small tree or shrub that is commonly found in North America, Europe, and Asia. It has been used for centuries as a natural remedy for various ailments such as heart problems, digestive issues, and high blood pressure. The leaves, flowers, and fruits of the Hawthorn plant are used to make supplements and teas that are reputed to have numerous health benefits.

Can Cats Eat Hawthorn?

Cats are obligate carnivores, which means that they require a diet that is high in protein and low in carbohydrates. They do not have the enzymes necessary to digest plant materials, and therefore, should not be given Hawthorn supplements or teas. Ingesting Hawthorn can cause gastrointestinal upset in cats, which can lead to vomiting, diarrhea, and dehydration. Cats that have underlying medical conditions such as heart disease or diabetes may be at a higher risk of experiencing adverse effects from Hawthorn.

What are the Toxic Components of Hawthorn?

Hawthorn contains several biologically active compounds such as flavonoids, oligomeric proanthocyanidins, and triterpenoids, which are responsible for its medicinal properties. However, some of these compounds can be toxic to cats if ingested in large amounts. The most common toxic components of Hawthorn are the cardiac glycosides, which are found in high concentrations in the leaves and flowers of the plant. Cardiac glycosides are a type of steroid that affect the heart and can cause arrhythmias, cardiac arrest, and death in cats.

What are the Symptoms of Hawthorn Toxicity in Cats?

The symptoms of Hawthorn toxicity in cats vary depending on the amount ingested and the time elapsed since ingestion. The most common symptoms include vomiting, diarrhea, lethargy, loss of appetite, and abdominal pain. In severe cases, cat owners may notice their cat having difficulty breathing, panting, collapsing, or having seizures. If you suspect your cat has ingested Hawthorn or is showing any of these symptoms, you should contact your veterinarian immediately.

How is Hawthorn Toxicity Diagnosed and Treated in Cats?

If your cat has ingested Hawthorn, your veterinarian will typically perform a physical examination and run diagnostic tests to determine the severity of the toxicity. These tests may include bloodwork, radiographs, electrocardiogram (ECG), or ultrasound. In severe cases, your cat may need emergency treatment such as oxygen therapy, intravenous fluids, or medications to stabilize their heart rate. If your cat has ingested Hawthorn but is not showing any symptoms, your veterinarian may recommend monitoring them at home and providing supportive care such as bland food, fluids, and rest.

How Can You Avoid Hawthorn Toxicity in Cats?

The best way to avoid Hawthorn toxicity in cats is to keep all supplements, teas, and herbal remedies out of their reach. If you have Hawthorn trees or shrubs in your yard, you should prevent your cat from accessing them. Additionally, you should always supervise your cat when they are outdoors and keep them away from any plants or flowers that you are unsure about. If you suspect that your cat has ingested Hawthorn, do not hesitate to contact your veterinarian even if they are not showing any symptoms.

Conclusion

Hawthorn may have numerous health benefits for humans, but it is not safe for cats to ingest. The cardiac glycosides found in Hawthorn can be toxic and potentially fatal to cats if ingested in large amounts. Cat owners should avoid giving Hawthorn supplements or teas to their feline friends and take precautions to prevent exposure to Hawthorn plants. If you suspect that your cat has ingested Hawthorn or is showing any symptoms of toxicity, contact your veterinarian immediately.
