Countless garden and house plants are poisonous to cats. The symptoms that should alert are numerous. It is therefore important to know how to spot them in time. In order to prevent a cat from being poisoned by plants, logic dictates that the owner should prevent his pet from nibbling on all types of plants. If it's easy enough when it comes to plants in the house, it's much less so when the cat is playing in the neighborhood gardens.

Plants: a real health hazard for cats
It is better to keep your cat away from Apocynaceae, Ericaceae, Liliaceae, Primulaceae or - in the family Solanaceae - Solaneae. The same goes for the Fabaceae including some leguminous plants... These numerous plant families, and many others, are to be avoided by cats, which represents thousands of plants as shown in the following few examples.

It is almost impossible to find an exhaustive list of plants that are toxic to cats. In order to preserve the health and, more broadly, the life of his animal, the owner must prevent his little companion from eating plants as soon as he is unaware of their effects on his organism. In case of doubt, he can refer to the veterinarian.
Intoxication of the cat by the plants: the symptoms
When a cat is poisoned by a house or garden plant, the risk of serious complications is extremely high. Depending on the case, the seeds, sap or latex contained in the plants can lead to irreparable health problems or even the death of the animal.
A cat poisoned by a plant can present disorders:
- Respiratory,
- Digestive,
- Neurological,
- Eyepieces,
- Cardiac,
- Cutaneous.
Many organs are likely to be affected such as the liver, kidneys, pancreas, intestines, lungs or heart. In some cases, it is not only the ingestion that causes a health problem for the cat but also the simple direct contact with the plant. This is for example the case of Caladium or Thuja.
Certain manifestations can put the flea in the ear of the cat's owner, namely :
- Irritation of the skin and mucous membranes,
- Hypersalivation,
- A tachycardia,
- Blood in the urine or hematuria,
- An edema,
- Suffocation,
- Convulsions,
- Diarrhea,
- A great inexplicable weakness,
- Apathy sometimes followed by episodes of hyperexcitability,
- Poor movement coordination is called ataxia,
- A paralysis.
Even more serious, the cat intoxicated by certain plants risks :
- Coma,
- Death.
It is fundamental to react in an emergency to save the cat that has ingested a toxic plant. If the animal presents one of the symptoms listed above, or any other strange manifestation, it must be taken care of imminently. This is imperative because a quick reaction can save his life.
The owner must provide all possible information so that the emergency veterinarian can diagnose the cause of the discomfort as quickly as possible and the plant that caused the poisoning. If possible, the owner of the animal should place a portion of the responsible plant in a plastic bag so that tests can be done by a veterinary clinic or laboratory to accurately identify it. Knowing the name of the plant with which the cat has become intoxicated is really very useful to ensure that the animal receives the proper treatment. Depending on the case, the veterinarian will administer an emetic, an antidote or other.
Only an animal health specialist or - in some cases, a pharmacist - can administer a medication to a cat intoxicated by an indoor or outdoor plant. It can be very serious to play the sorcerer's apprentice: you do not give any substance to your animal that shows all the signs of poisoning or intoxication.
It is however necessary to put things into perspective. If all cats were at risk of becoming intoxicated every time they graze or taste a dangerous plant, it would be a long time ago that this animal would have totally disappeared from the planet. Finally, if we refer to the experience of veterinarians, cases of serious plant poisoning in cats are not so numerous and that's fortunate.
Nevertheless, it is better to avoid taking risks and give preference to plants that are not dangerous for pets.
Non-toxic plants for cats
Having a cat does not imply that you have to give up all the plants, whether in the house or in the garden. Fortunately, humans and animals need plants. In any case, it is very reassuring to know that some plants do not present any danger for the cat and indoor and outdoor plant enthusiasts can continue to indulge in their pleasure.
These plants that are not dangerous for cats are not very numerous. In this group, we find for example :
- Bamboo,
- Basil,
- Lavender,
- The orchid,
- The rose tree,
- The Saintpaulia or Cape Violet,
- The succulents.
It is therefore possible to have a beautiful garden, a pleasant and shady terrace as well as a green interior while owning a cat without risking to poison it.
What about cat herbs?
You can find catnip trays in the shops. This one is necessary for the animal's well-being. It has relaxing powers and digestive virtues.
There is also a mixture called cat grass, consisting of mint, Actinidia polygama or matatabi, sometimes Teucrium marum, a plant nicknamed Cat Germandrée. In the presence of this composition, the cat rolls on the herbs in full ecstasy because these plants exhale a very powerful perfume that does not leave the animal indifferent.
These are two solutions without any danger for cats and kittens. This type of plant preparation can be purchased regularly, which will divert the cat from house and garden plants.
We realize that a cat's good health is ultimately a matter of little importance. This is why it is highly recommended to insure your little companion with an animal health insurance company. In case of need, emergency care, medication, surgery or accident, the owner will not have to pay much. The pet insurance offers different solutions to be reimbursed at least partially for expenses incurred for all veterinary or even preventive procedures. A cat insurance comparator allows you to receive in a few minutes several free and non-binding quotes.
