Houseplants That Are Toxic to Cats

Houseplants can beautify any home. They make your living environment more attractive and can even improve the air quality of your home. These beautiful creatures can even reduce anxiety and depression, so some believe that keeping plants is a form of therapy in itself.

But if you have a cat in your home, you have to avoid many plants because they may be poisonous to your cat, especially since cats are known for being mischievous and like to chew everything. Therefore, in this article from TooPlant, we will introduce you to 15 popular indoor plants that are poisonous to cats, so that you know whether they are poisonous to your cat or not!

Why do cats eat plants, and should I be worried?

One of the motivations for cats to eat plants is the existence of a mass of herbal. The worst that can happen to your cat is that the plant eaten is poisonous.

It’s not a staple diet, but consuming the plant helps the digestive system function and move furballs through the digestive system.

  • If the cat secretes a lot of saliva after eating a harmful plant or has digestive problems, be sure to consult a veterinarian.
  • If you find out which plant the cat ate, take that plant with you to the vet or tell the vet its name.
  • After eating a poisonous houseplant, do not give the cat anything, neither water nor food.

What are some toxic houseplants to cats?

Unfortunately, some houseplants are poisonous and can cause allergic reactions, poisoning and even death in cats. Plants have different effects on animals. Keeping poisonous houseplants alone does not harm us and only in special cases causes children or animals to be poisoned.
