Why Are Hydrangeas Poisonous to Cats?

Chemicals in Hydrangeas

Hydrangeas contain chemicals called cyanogenic glycosides, which can be toxic to cats and other animals, including humans. When a cat chews or ingests any part of the plant, the cyanogenic glycosides are released, which can lead to symptoms such as vomiting, diarrhea, and lethargy. Cyanogenic glycosides can release cyanide when they come into contact with specific enzymes in the digestive system. Although the level of toxicity varies based on the specific species of hydrangea and the amount ingested, it is essential to note that any amount of cyanide can be dangerous for cats.

Release of Cyanide

Cyanide is released from hydrangeas when the cyanogenic glycosides in the plant come into contact with certain enzymes in the digestive system. Cats can be exposed to cyanide if they chew or ingest any part of a hydrangea plant. Cyanide is a highly toxic substance that can interfere with cellular respiration, leading to serious health issues.

Toxicity Varies by Species

There are over 75 types of hydrangeas, and all of them contain toxins that can be harmful to cats if ingested in large quantities. While some hydrangea varieties may be more toxic than others, it is crucial to understand that any type of hydrangea can pose a risk to cats. The level of toxicity varies depending on the species, with the Bigleaf hydrangea (Hydrangea macrophylla) being the most toxic to cats. If you have hydrangeas in your home or yard, it is essential to take precautions to keep your cat safe.

Most Toxic Type of Hydrangea

The Bigleaf hydrangea (Hydrangea macrophylla) is considered the most toxic type of hydrangea for cats. This plant contains a substance that can cause vomiting, diarrhea, and lethargy if consumed in large quantities. In addition, the flowers of the Bigleaf hydrangea contain a higher concentration of the toxin compared to the leaves or stems. It is crucial to ensure that your cat does not have access to this particular type of hydrangea to prevent potential poisoning.

Toxic Parts of Hydrangea

All parts of a hydrangea plant, including the flowers, leaves, and stems, contain cyanogenic glycosides and can be toxic to cats if ingested. However, as mentioned earlier, the flowers of the Bigleaf hydrangea are particularly dangerous due to their higher concentration of toxins. It is crucial to keep your cat away from all parts of hydrangea plants to avoid potential poisoning.

These can include restlessness, tremors, weakness, confusion, abnormal heart rhythms, and even coma in severe cases. If you notice any unusual behaviors or signs of distress in your cat after potential exposure to hydrangeas, it is essential to seek immediate veterinary attention.

What To Do If Your Cat Eats a Hydrangea

Immediate Action

If you see your cat nibbling on a hydrangea plant, it is important to remove them from the area immediately to prevent further ingestion. This can help minimize the potential toxicity and prevent further complications. However, do not attempt to induce vomiting without consulting a veterinarian, as it can be dangerous to do so without professional guidance.

Contacting a Veterinarian

After removing your cat from the hydrangea plant, contact your veterinarian right away to inform them of the situation. They will be able to provide you with further instructions on what to do next based on the specific circumstances. They may recommend bringing your cat in for a thorough examination or provide guidance on monitoring for any signs of illness.

Monitoring for Illness

Following exposure to hydrangeas, it is important to closely monitor your cat for any signs of illness or abnormal behavior. If you notice symptoms such as vomiting, diarrhea, lethargy, or any other concerning signs, it is crucial to seek veterinary care immediately. Prompt treatment can help mitigate the potential effects of hydrangea poisoning.

Plant Sample for Identification

If possible, bring a sample of the hydrangea plant with you when you visit the veterinarian. This can help them identify the specific species of hydrangea and determine the best course of treatment. Proper identification will enable them to provide targeted care and support for your cat.

Additionally, supportive care such as intravenous fluids and medications to manage symptoms may be necessary. Every case may differ, and the appropriate treatment plan will depend on the severity and individual needs of your cat.

How to Prevent Hydrangea Poisoning in Cats

Keeping Hydrangeas Inaccessible

To prevent hydrangea poisoning in cats, it is crucial to keep all hydrangea plants inaccessible to them. This may involve placing the plants on high shelves, using hanging baskets, or keeping them behind closed doors in rooms that are off-limits to cats. By creating physical barriers, you can minimize the risk of unintentional ingestion.

Alternative Safe Plants

Consider using alternative plants in your home or yard that are safe for cats. There are numerous cat-friendly plants available that can add beauty to your space without posing a risk to your feline companion. Research cat-safe plants and choose ones that suit your preferences while ensuring the safety of your cat.

Supervising Outdoor Time

If your cat spends time outdoors, it is crucial to supervise them closely and keep them away from any plants that may be toxic. This includes not only hydrangeas but also other potentially harmful plants. By closely monitoring your cat’s outdoor activities, you can prevent accidental ingestion and reduce the risk of poisoning.
