What plants are toxic to cats? Many pet parents keep some common and beautiful plants in their homes without realizing that they are toxic to cats.
Not all household plants will be fatal if chewed or eaten, but there are some can kill your dearest feline friend. Never assume that a cat will try not to eat a poisonous plant. Cats are often taken to the veterinarian due to eating toxic plants rather than other animals such as Dogs.
In this article, we discuss many common plants that pose a health risk to your beloved cats. So, make sure that you don’t bring these poisonous plants into your home or garden, where kitty plays.
If you already have them in your home, it would be best to remove them as soon as possible. Many of these species are usually kept as household plants, so we guess some would surprise cat parents.

Plants parts which are toxic to cats:
Suppose if any plant is poisonous to cats, never assume that all parts of that plant are poisonous. For example, Daffodils have their poison only in bulbs or flowers, not in stem shoots or roots. Similarly, some plants have toxic roots, but their fruit and flowers are safe for felines. Also, some parts of the plant may have higher levels of toxicity than other parts.
Toxin amounts can vary widely from plant to plant. In some cases, eating small amounts can have devastating consequences on cats, while in some cases, a relatively large number of plants must be consumed for symptoms to develop.
General symptoms to see in cats after plant poisoning:
Because many plants are irritants, most symptoms are caused by irritation or inflammation, such as swelling, redness, or itching of the skin, eyes, or mouth.
When the GIT tract’s deeper parts, like the stomach and intestines, are infected with irritants or poison, vomiting and diarrhoea result from these consequences.
If any toxin from a plant affects a particular organ, its symptoms will be primarily related to that organ:
Kidney:
If the kidney is affected the cat will display signs of excessive urination.
Intestines & Stomach:
If the intestines and stomach are affected the cat will display the poisoning symptoms by vomiting.
The cat might also suffer from diarrhoea as a result from poisoning if the small and large intestines are affected.
Throat, Oesophagus, and mouth:
If the cats mouth, throat or oesophagus is affected by poisoning the cat will will have difficulty swallowing or digesting food.
Airways:
The cat might have difficulty breathing is the airways are affected by the poisoning.
Heart:
The cats heartbeat can become; slow, fast, or irregular if the heart is affected by the poisoning.
What Should You Do If You Think Your Cat Is Suffering From Poisoning?
If you see that your cat eats a plant and you believe it is poisonous or, or if you think that your cat has eaten such a plant, take it to your veterinarian immediately.
Where possible take note or an image or the plant to show your vet. This way they will know exactly what treatment to give. As mentioned above, different plant toxins affect different parts of the cat’s body.
What To Do FIRST Before Taking Your Cat To The Vet For Plant Poisoning.
- If you can do this safely, remove any plant material from your cat’s skin, hair, and mouth.
- Keep your cat in a safe environment for close monitoring.
- Call the Pet Poison Helpline, Animal Poison Control, or your local veterinary practice.
- Identifying plants to determine treatment is difficult, so general poison treatment is given to your pet to save his/her life.
- If you do not know the name of the poisonous/toxic plant, your cat has encountered, bring a small sample of the same plant or plant material that your cat vomited with you to the veterinarian. If you can, obtain a sample take a photo to take with you to the clinic.
Diagnosis of Poisonous Plants:
The most proper diagnosis is made by identifying the toxic plant itself. Your veterinarian will also perform a physical examination of your cat and give the necessary tests to determine your cat’s overall health.
These tests are critical if the toxic plant’s identification is unknown or if the identified plant is known to target internal organs.
How To Protect Your Cat Against Plant Poisoning:
Consumption of some poisonous or toxic plants can be fatal for cats if treatment is delayed.
Be sure to follow your Vets instructions and ask any questions you may have.
Take whatever steps you can to protect your cat from exposure to poisonous plants. This includes removing such plants from your home and keeping your cat indoors, or closely monitoring outdoor activities.
