Why is aloe both toxic and safe for cats?

The aloe plant is considered to be dangerous to cats because of its outer part (the skin of the leaves) which contains saponins and anthraquinones (ASPCA).

In more simple terms, it contains a sticky latex, which has strong purgatory properties and leads to digestive distress and severe diarrhea.

However, also according to ASPCA, “the gel is considered edible”. It means that the gooey gel inside the thick leaves, the part with the healing properties, is safe and edible for cats.

How can a cat absorb a toxic part of aloe?

Because the toxic substances are based in the skin of the aloe vera leaves, a cat can absorb them by eating or chewing on the leaves.

In the cat products, watch out for the ingredient “Aloes”. Aloes consist of latex, that is extracted from the skin of aloe leaves.

A cat will not become poisoned by the aloe vera plant through a skin/coat contact with a plant or by smelling it (something that can happen with other plants, such as lavender).

How can a cat absorb a safe part of aloe?

When you see aloe vera as an ingredient in various cat products, for example, in a cat shampoo, don’t panic. It’s most likely the aloe vera gel, that is safe for cats and has potent healing properties.

A cat can absorb the aloe vera gel by digesting it (oral intake) or topically (dermal intake).

It’s safe to put the aloe vera gel directly from the broken leaves onto your cat’s skin. It’s also fine for your cat to eat the gel.


How to keep a cat safe from aloe

To keep a cat safe from the toxic parts of aloe, simply keep away the aloe vera plants out of your cat’s reach so that she cannot gnaw on them and eat them.

You could also try to spray the plants with a smell cats hate, for example, vinegar or a special cat repellent spray.

How to treat a cat poisoned with aloe

Don’t panic if you saw your cat gnawing on the aloe vera leaves a little. Small quantities of digested aloe outer parts will likely cause only a small discomfort.

A cat would need to consume a large quantity of foliage to become very sick. A large quantity of latex in the digestive system could lead to severe diarrhea which could cause dehydration that could be lethal.

If that’s the case and your cat feels very bad and has strong diarrhea then call your vet or ASPCA’s Animal Poison Control Center (888-426-4435) immediately. Your cat may need to be treated with IV fluids to survive.

Luckily, the aloe vera plant is bitter in taste which is not attractive to cats so the chances that your cat will eat a lot of the bitter leaves is rather small.
