​Aloe is quite a popular and populous genus that consists of quite a few different species. These succulents have thick and fleshy leaves that are green or bluish-gray-green in color with white flecks. Although aloe vera has quite a common place in modern medicine and remedies, it’s a toxic plant for cats if ingested. The main reason for this is the existence of the chemical saponin in the aloe, which causes serious problems in a cat when ingested.

​Symptoms​: ​​abdominal pain, lethargy, nausea, skin irritation, vomiting, diarrhea, tremors

​Euphorbia​ (Various)

​The Euphorbia family is one of the most commonly known poisonous succulent families. It’s the fourth largest genus of flowering plants and is found in certain regions of Africa and Madagascar. Although there are many different succulents in the Euphorbia family, they should all generally be avoided. These succulents contain a white sap that irritates skin and can cause a rash. When ingested, this sap can irritate the stomach of a cat.

​Kalanchoe (Various)

The harmful chemical in Kalanchoes is bufadienolides cardiac glycosides, and this causes irregular heartbeats. Most times when this plant is eaten, it only results in mild irritation. However, it is dangerous in large amounts.

​Symptoms​: ​​vomiting, diarrhea, lethargy, weakness, abnormal heart rate (rare)

​How To Keep Cats From Eating Succulents

​Whether the succulents in your house are poisonous to cats or totally harmless, you obviously don’t want your cat eating your succulents in the first place. Unfortunately this is a bit of a problem as cats are frequently attracted to the chewy green leaves practically beckoning them over. For the sake of the health of your cat and succulents alike, how does one keep their cat from eating these adorable plants?

​Make Your Succulents Stink

​Since cats have a very acute sense of smell, you can use that characteristic to keep them away from your plants. There are several simple and natural ways that you can make your succulents smell very unappealing. Cats can’t stand the smell of citrus, so adding a lemon peel to the soil of your succulents will do wonders keeping them away. A small sprinkle of cayenne pepper around the plant will also keep a cat quite far away.

​Add Cat-Specific D​eterrents 

​If the more natural route of using lemon peels and cayenne pepper doesn’t deter your cat from munching on your succulents, you may have to break out the big guns. Fortunately, there are a few non-toxic sprays that are designed to keep pets away from houseplants. An alternative to this would be a spray bottle filled with 1 part vinegar and 3 parts water.

​Choose Succulents That Cats Hate

​If your cat is dead-set on eating your succulents, you can go back to square one and only own plants that cats hate. Any plants with thorns such as cactus will mostly go untouched by cats once they experience the thorns themselves. Some aloe vera are also quite spiky, but they should generally be avoided all together due to their toxicity. Of course, you could ​also go for plants that aren’t succulents but still deter cats such as rosemary.

​Place Your Succulents In Good Locations

​If you can, placing your plants out of reach of your cat will keep them from getting eaten. If your cat isn’t allowed into a bedroom, bathroom, or office that gets a lot of light, then that might be a good location for your succulents. Height will also keep them out of reach, such as up on a book shelf or in hanging baskets. You’ll have to find a balance between keeping the plant hidden from cats but still visible to you.

​What To Do If A Cat Eats A Succulent

​In short — don’t panic! If your cat eats a succulent, even if it’s considered a poisonous succulent for cats, it’s almost guaranteed that your cat will be fine.

The side effects that cats will experience after ingesting toxic succulents are simply their bodies’ attempts to purge the succulent from their symptom. If you notice your cat eating your succulent, the best thing that you can do is take the plant away, give your cat some food and water, and monitor them for a couple of hours.

​No succulents will kill a cat with just one nibble. Some types, such as Kalanchoe, can potentially be deadly in large amounts, but this is extremely rare. Most cases will simply result in a cat feeling unwell for a little bit, maybe puking or having a loose bowel movement, and then returning to normal in a couple of hours.

However, if you’re concerned about your cat’s health, it’s always recommended that you contact their vet immediately! It’s always better to be safe than sorry when it comes to the health of your furry feline friend. Cats and succulents are both so enjoyable — you wouldn’t want one to be the demise of the other.
