Why aloe vera is toxic to cats
The yellow latex just beneath the leaf skin contains anthraquinones such as aloin, which are strong laxatives, plus saponins that irritate the gut.
What to do if your cat ate aloe vera
- Remove plant pieces from your cat's mouth and move cats away from the plant. Wipe sap or pollen off the fur and paws with a damp cloth.
- Call your vet or animal poison control for advice: ASPCA Animal Poison Control: (888) 426-4435 · Pet Poison Helpline: (855) 764-7661.
- Identify the plant. Take a photo or bring a piece (or the plant label) to the vet, and estimate how much was eaten and when.
- Do not make your cat vomit unless a vet tells you to. Home remedies such as hydrogen peroxide or salt can cause serious harm, and hydrogen peroxide is not safe for cats.
- Watch for vomiting, diarrhea, lethargy. Go to a vet if signs are severe, last more than a day, or your cat has trouble breathing or swallowing.
Treatment and outlook
Supportive care for vomiting and diarrhea, with fluids if your pet becomes dehydrated.
How to keep your cat away from aloe vera
- Place aloe vera on high shelves or in hanging planters away from furniture cats can climb, or in a room your cat cannot enter.
- Give your cat something better to chew: a pot of cat grass or catnip often distracts cats from houseplants.
- Pick up fallen leaves, petals and pollen promptly, and empty vases where pets can reach them.
