Understanding Hydrangea Toxicity in Cats
Feb 25,2025 | puaintapets
Hydrangeas are beautiful flowering plants often seen in gardens and homes, beloved for their vibrant colors and hearty growth. However, if you have a cat, you may be concerned about whether these flowers are safe for your feline friend. While hydrangeas are non-toxic to humans, the situation is different for cats. In this article, we will explore whether hydrangeas are poisonous to cats, the symptoms of poisoning, and what steps to take if your cat consumes any part of this plant.
Are Hydrangeas Poisonous to Cats?
Yes, hydrangeas are toxic to cats. The plant contains a substance called cyanogenic glycosides, which, when ingested, can release cyanide—a potent toxin. While hydrangea poisoning is not typically fatal, it can cause serious health issues for your cat if consumed in significant quantities. All parts of the plant, including the flowers, leaves, and stems, are toxic to cats.
Hydrangea poisoning in cats is generally more common when cats are curious and nibble on plants in their environment. This can happen if your cat is allowed outdoors or has access to houseplants. Understanding the risks and knowing what to do in case of exposure is crucial to keeping your cat safe.
How Does Hydrangea Poisoning Affect Cats?
When a cat ingests parts of a hydrangea plant, the cyanogenic glycosides are metabolized into cyanide in the digestive system. Cyanide disrupts the body’s ability to use oxygen, leading to a variety of symptoms. The severity of poisoning depends on the amount of the plant consumed and the size of the cat. In mild cases, symptoms may be limited to gastrointestinal upset, while more severe poisoning can cause neurological and respiratory symptoms.
Symptoms of Hydrangea Poisoning in Cats
If your cat has eaten hydrangea, it’s essential to look for symptoms of poisoning. Common signs of hydrangea toxicity include:
I. Gastrointestinal symptoms
Vomiting: This is one of the most common symptoms and the cat may vomit frequently, the vomit may contain undigested food or bile.
Diarrhea: the cat may exhibit diarrhea and the feces may be watery or with mucus.
Abdominal pain: the cat may show abdominal discomfort such as curling up and unwillingness to move.
Loss of appetite: the cat may lose interest in food or even refuse to eat.
II. Nervous System Symptoms
Lethargy: the cat may become more lethargic and depressed than usual.
Depression: the cat may show low mood and less interaction with its surroundings and owner.
Weakness: the cat may show symptoms such as weakness in the limbs and unsteady walking.

How to Save a Cat from Hydrangea Poisoning?
The following is how to save a cat from hydrangea poisoning:
1.First aid measures
-
Induce vomiting
If your cat is found to have ingested hydrangea shortly afterward, you can try to induce vomiting. You can use 3% hydrogen peroxide solution, 1-2 ml per kg of body weight, orally or by gavage to stimulate the cat to vomit. However, it should be noted that emetic should be carried out under the guidance of a veterinarian and should not be used if the cat is already vomiting, unconscious and other serious symptoms.
-
Gastric lavage
If vomiting is unsuccessful or the cat has been poisoned for a long time, the cat should be taken to the veterinary hospital for gastric lavage as soon as possible. Gastric lavage can use saline or warm soapy water to rinse the stomach repeatedly to remove the poison in the stomach.
-
Conducting diarrhea
In order to accelerate the expulsion of the poison, the cat can be given an appropriate amount of laxative after gastric lavage, such as sodium sulfate or magnesium sulfate, etc., but attention should be paid to the dosage and the method of use, to avoid causing harm to the cat.
2.Treatment
-
Medication
Depending on the cat's symptoms and the degree of poisoning, the veterinarian may give appropriate medication. Such as antiemetic, antidiarrheal, hepatoprotective and detoxification drugs.
-
Supportive treatment
Including intravenous fluids, supplemental nutrition, etc. Intravenous fluids can correct dehydration and electrolyte disorders caused by vomiting and diarrhea in cats, and maintain the acid-base balance in the body. At the same time, according to the cat's physical condition, vitamins, amino acids and other nutrients can be supplemented appropriately to promote the cat's recovery.
-
Symptomatic treatment
If the cat has serious symptoms such as respiratory distress and convulsions, the veterinarian will take appropriate symptomatic treatment measures. Such as oxygen, the use of sedatives and so on.
3. Precautions
-
Prompt medical attention
Once you find that your cat has symptoms of hydrangea poisoning, you should take your cat to the veterinary hospital immediately.
-
Provide accurate information
When seeking medical treatment, you should provide the veterinarian with information such as the time and quantity of the hydrangea that the cat accidentally ingested, as well as basic information such as the cat's weight, age and health condition, so that the veterinarian can accurately diagnose and treat the cat.
-
Close observation
During the course of treatment, the cat should be closely observed for changes in symptoms, such as the frequency and degree of vomiting and diarrhea, mental state, appetite, etc. Any abnormality should be promptly notified to the veterinarian.
-
Prevention of recurrence
After the cat recovers, care should be taken to place the hydrangea and other poisonous plants in a place that is inaccessible to the cat to avoid accidental poisoning of the cat again. At the same time, daily observation and care of the cat should be strengthened to ensure the health of the cat.
What to Do If Your Cat Accidentally Comes in Contact with a Hydrangea?
If your cat accidentally comes into contact with hydrangeas, you can treat it as follows:
1. Immediate isolation
Isolate the cat from the hydrangea to prevent it from coming into contact with it again or accidentally eating it.
2. Clean the contact area
Use water or pet-specific cleaning products to clean the parts of the cat that come into contact with the hydrangea, such as paws and mouth, to remove any pollen or sap that may remain.
3. Close observation
Observe the cat for any abnormal behavior or symptoms, such as vomiting, diarrhea, drooling, lethargy, shortness of breath, etc. If there is any, seek medical attention immediately.
Preventive measures
- Understand plant toxicity: In the process of keeping cats, understand which plants are toxic to cats, such as hydrangeas, lilies, daffodils, tulips, etc., and try to avoid planting or placing these plants at home.
- Place in a safe location: If there are toxic plants such as hydrangeas in your home, you should place them in a place where cats cannot reach them, such as a high place, a closed space or use shelves that cats cannot climb.
- Choose non-toxic plants: You can choose some plants that are non-toxic to cats to decorate the home environment, such as cat grass, mint, golden money grass and African violets.
- Regularly check the environment: Regularly check whether there are any poisonous plants or their fallen petals, branches and leaves in your home that cats can access, and clean them up in time.
- Train the cat's behavior: Through training, let the cat know which plants are not to be touched. When the cat is near the poisonous plants, you can issue a command or use a sprinkler to spray them lightly, so that they will know that this is an undesirable behavior.
