Are succulents toxic to cats?

The short answer is yes, some succulents are bad for cats when ingested.

Toxicity can range from mild to severe, and I will describe what can happen if you cat chews any one of these plants.

Luckily, there are just a few succulents that are harmful for cats. The majority of succulent plants are non-toxic if ingested by a cat.  I have an article dedicated to cat safe succulents, so check it out!

And after you read this post and take a good look at the provided pictures, you will remember forever which succulents should not be brought to your house if you have an indoor cat.

Let’s get to it!

Succulents toxic to cats


aloe vera

This one is a bummer! Known for centuries for its healing properties, widely used in natural products, believe it or not, aloe vera is a bad plant to be chewed by your cat.

Why,  you wonder? 

A chemical aloin in aloe vera when ingested acts as a laxative and can cause diarrhea, cramps, vomiting, tremors in pets. Its toxicity for pets is moderate to strong. When your cat eats a piece of aloe vera, you should notify your veterinarian.

Additionally, according to the latest toxicology report, aloe vera may have tumor-promoting activities. 

Also, if your cats are allergic to latex, aloe vera can cause skin irritation.

So, keep aloe vera away from your kitty, and go easy on this plant for your own use too.


coral cactus - toxic for cats

Similar in appearance to ocean coral, Coral cactus (Euphorbia lactea) is actually two succulent plants joined together to create an unusual look.

And though it looks cool and makes a great “conversation piece”, if you have cats, Euphorbia lactea  is another succulent to avoid. When ingested by a cat it can cause mouth irritation and vomiting.


jade plant - toxic to cats

Though the Jade plant is considered to be a great indoor plant for attracting money luck to your house, it’s not so lucky for your cat to chew on it. Jade is mildly toxic and can cause vomiting in a cat.


kalanchoe toxic to cats

Kalanchoes are beautiful soft succulents that, unfortunately, are not safe for cats. They can cause gastric upset and, rarely, abnormal heart rhythm.


succulents poisonous to cats

Snake Plant or Mother-In-Law’s Tongue that has succulent leaves is also known for its mild toxicity to cats when chewed on, so avoid this plant around cats.


string of pearls toxic to cats

Simply put – cats and string of pearls plants don’t go well together. All parts of this plant are toxic to cats and can cause liver failure when ingested. So, just don’t bring a string of pearls succulent home if you have a cat.
