Yes, Dog Hobble is toxic to cats. Commonly known by other names such as Dog Laurel, Fetter Bush, and Black Laurel, this evergreen shrub contains compounds like arbutin glucoside and various grayanotoxins, including andromedotoxin, acetylandromedol, rhodotoxin, and asebotoxin. When ingested by cats, these toxins can inhibit sodium channels from deactivating by attaching to them in the body’s cells. This action can lead to a series of serious health impacts, potentially culminating in cardiac arrest and respiratory failure.

Clinical Signs of Dog Hobble Poisoning in Cats
If a cat comes into contact with, inhales the scent, or ingests the Dog Hobble plant, it can exhibit various clinical symptoms. The extent of these symptoms is largely influenced by the amount of the plant consumed. It’s essential to understand that while poisoning incidents from Dog Hobble in cats are infrequent, they are serious and can be fatal. Let’s delve deeper into the symptoms and understand the reasons behind each:
- Excessive Salivation: This occurs due to the immediate irritation caused by the plant’s toxins on the oral tissues, signaling the body to produce more saliva as a protective mechanism.
- Perspiration around the Nose and on Foot Pads: The toxins affect the cat’s autonomic nervous system, leading to increased perspiration as the body tries to expel toxins.
- Vomiting & Diarrhea: The toxins from the plant can irritate the gastrointestinal tract, prompting the body to expel them through vomiting and diarrhea.
- Dizziness, Weakness, & Twitching: These symptoms are indicators of the neurological impacts of the toxins, affecting the cat’s central nervous system.
- Tingling or Burning Sensation in the Extremities and around the Mouth: This results from the direct effect of the toxins on nerve endings, creating sensations of tingling and burning.
- Low Blood Pressure & Sinus Bradycardia: The toxins can lead to reduced heart rate and subsequent lowering of blood pressure, affecting the circulation and oxygen delivery in the cat’s body.
For cats that ingest a significant amount of Dog Hobble, more severe symptoms arise:
- Severe Muscular Weakness: This can be attributed to the disruption in normal nerve function, affecting muscle control and strength.
- Bradycardia: A further reduction in heart rate, which can have life-threatening consequences if not treated immediately.
- Ventricular Tachycardia & Nodal Rhythm or Wolff-Parkinson-White Syndrome: These are severe cardiac abnormalities caused by the profound impact of the toxins on the heart’s electrical system.
- Coma: Due to significant neurological and systemic disturbances, a cat can slip into a coma, a deep state of unconsciousness.
- Death: In severe cases and without timely intervention, the combined effects of these symptoms can sadly lead to the death of the affected cat.
If you notice any of these symptoms in your cat after contact with Dog Hobble, it’s imperative to seek immediate veterinary care.
