Are some plants poisonous to cats?
Cats love to explore and experience new things. Particularly, cats love sniffing and chewing on plants. Unfortunately, some plants contain toxins that pose danger to cats.
As of today (2023) ASPCA, The American Society for the Prevention of Cruelty to Animals, lists 424 plants that are poisonous to cats.
It’s quite unlikely that the cat’s instinct would allow a cat to eat a toxic plant. Nevertheless, it’s still worth keeping the poisonous plants away from your pet.
If you’re worried that your cat will eat poisonous plants while outside, you can keep her on a harness. Here is a list that will help you to choose the best cat harness no escape.
The infographic below shows the most beautiful plants and flowers that are at the same time poisonous to cats. Be careful not to give your furry friend too much exposure to these beauties.

How to protect your houseplants from cats?
The grass is an important ingredient in the cat’s diet. It helps to regurgitate ingested fur. If an indoor cat doesn’t have access to grass, she will be desperate to nibble on just any plant she has access to.
If you don’t want to get rid of some of your toxic house plants, but you are still worried that your cat will eat them, provide your cat with a small box of grass so that she has something healthy to chew on and she is not tempted to eat your poisonous plants.
You may also try spraying your plants with diluted lemon juice and see if that works to deter your cat.
What are the symptoms of cat poisoning?
According to PetMED, the symptoms of cat poisoning are as follows:
– Difficulty breathing (if the airways are affected)
– Drooling or difficulty swallowing (if the mouth, throat, or esophagus is affected)
– Vomiting (if the stomach or intestines are affected)
– Diarrhea (if the intestines or colon are affected)
– Excessive drinking and urinating (if the kidneys are affected)
– Fast, slow, or irregular heartbeat (if the heart is affected)
What to do if your cat gets poisoned?
If you think your cat got poisoned, seek immediate advice from a veterinary professional.
In the meantime, if you think the irritant may still be on the cat’s fur, make a temporary Elizabethan collar from cardboard and put it on your cat immediately. It will prevent your cat from grooming itself and potentially consuming even more of a poisonous irritant.
