  • Sunscreen
  • Lotion
  • Burn ointment
  • Cleansing wipes
  • Makeup
  • Yogurt
  • Juice

While this plant is popular in medicinal purposes, cosmetic, and even edible products for humans, is Aloe Vera toxic to cats?


If you’re hoping to bring home a new house plant, get the essential facts before introducing it to your pet.

Are Aloe Plants Toxic To Cats Our Furry Friends?

Is Aloe toxic to cats? Research shows that cats might know it’s toxic to them. But, they may choose to bite the toxic plant anyway.

Sandra Sawchuk, a clinical instructor at the School of Veterinary Medicine, explains why this happens:

“Some plants, notable catnip, make cats feel good. Some cats also like spider plants, which contain compounds related to opium. Or cats learn that certain plants will act as a purgative, causing them to vomit if they have an upset stomach.” [source]

Are Parts Of The Aloe Plant Poisonous or Toxic?

Aloe leaves will leak a clear liquid called latex when cut. Not to be confused with the squishy aloe vera gel that fills out the leaves, the runny latex contains all the components that are toxins to cats.

Aloe gel, in comparison, is not harmful. In fact, some pet ointment manufacturers use the gel in their products to make Aloe safe for cats.

What Are The Symptoms Of Poisoning?

When a cat bites into an Aloe plant, the toxins irritate its mouth. As the animal ingests the latex, their colon will feel the worst effects.



  • Loss of appetite
  • Muscle cramping
  • Diarrhea
  • Vomiting

These are all severe signs that your cat has Aloe poisoning.

If your cat is showing any of these symptoms, seek help immediately. A veterinarian can diagnose the cause of the upset stomach and help protect your pet from further harm.

How To Protect Your Cat From Aloe

If your cat is prone to nibbling on various house plants, keep your Aloe out of reach. A hanging planter is an excellent option.

You can also discourage your cat from nibbling plants by providing plenty of food, fresh water, and toys for entertainment. A pet that gets plenty of stimulation is less likely to chew out of boredom.

Linda Naeve, an Urban Agriculture Specialist at Iowa State University Extension, suggests offering cat-friendly plants to your feline instead:

“Cat grass, sold at pet stores and garden centers, is a healthy alternative to turfgrass and other plants. Most commercially available cat grass seed is common oats, Avena sativa. But, it may also be packaged as a blend of oats, wheat, and rye grass.” [source]

Final Thoughts

Aloe can be a lovely and functional addition to your space. While it’s a convenient home remedy for scrapes and burns, its effects on humans and their pets are very different.

Is aloe bad for cats? If your cat shows signs of Aloe poisoning, such as vomiting, diarrhea, and loss of appetite, take them to the vet right away.

As long as you know the facts and take safety measures with this plant, you should be able to avoid an emergency trip.

Is Aloe poisonous to cats? Yes, but the plant and the animal can live together in harmony.
