Is Aloe Vera Safe for Dogs and Cats?
By the VetVerdict team · Last updated October 18, 2026 · General information, not veterinary advice
Dogs
ToxicMildThe gel and latex in aloe vera leaves can cause vomiting, diarrhea, and lethargy in dogs, though it's rarely life-threatening.
Cats
ToxicMildCats can have the same digestive upset from chewing aloe vera leaves.
What's in the leaf
The clear gel inside aloe is not the main concern. It is the yellowish latex just under the leaf's skin, which contains saponins and anthraquinones that irritate the gut and act as a strong laxative.
Houseplants, juices and gels
Cats in particular like to chew houseplants, and a chewed aloe leaf is the usual source. Aloe juices and supplements marketed to people are not intended for pets. Topical aloe gels may contain other ingredients, so check the label and stop your pet from licking treated skin.
Signs to watch for
- Vomiting
- Diarrhea
- Lethargy
- Loss of appetite
- Tremors in some cases
- Changes in urine color have been reported
Most cases are mild to moderate, but repeated vomiting or a large amount deserves a call to your vet.
What to do
Remove the plant, gently rinse your pet's mouth, and call your vet or poison control if your pet ate more than a nibble or has ongoing symptoms. Bring any product label with you.
Safer alternatives
Safer greenery for pet homes includes spider plants and cat grass; confirm others against the ASPCA's plant list.
