Is Christmas Cactus Poisonous to Dogs?

The ASPCA lists Christmas Cactus (Schlumbergera bridgesii) as non-toxic to dogs, cats, and horses, with no toxic principles identified. The plant contains no compounds known to poison dogs. However, non-toxic does not mean entirely without risk: ingesting a large amount of the fibrous plant material can still cause mild, self-limiting gastrointestinal upset such as vomiting or diarrhea, simply from the indigestible fiber irritating the stomach and intestines. Pet Poison Helpline notes the related related holiday cacti may cause mild signs from the fibrous material rather than a toxin. The stems and flowers pose a minor choking or GI-obstruction hazard for small dogs or aggressive chewers if a large piece is swallowed. Soil, fertilizer, pesticides, or systemic insecticides applied to the plant can themselves cause illness, so keep treated plants out of reach. If your dog nibbles a leaf or two, watch for short-lived stomach upset; persistent vomiting, lethargy, or signs of a blockage warrant a call to your veterinarian. Take care not to confuse the true Christmas Cactus with unrelated, genuinely toxic holiday plants such as poinsettia, holly, mistletoe, or amaryllis.

Is Christmas Cactus poisonous to dogs?

No. The ASPCA classifies Christmas Cactus (Schlumbergera bridgesii) as non-toxic to dogs. It contains no known toxic principles, so it will not poison a dog that chews or eats it.

What happens if my dog eats a Christmas Cactus?

Most dogs have no reaction. Eating a large quantity of the fibrous stems or flowers may cause mild, temporary gastrointestinal upset such as vomiting or diarrhea from the plant fiber, not from poisoning. Signs usually resolve on their own. Contact your vet if vomiting is repeated or your dog seems unwell.

Is Christmas Cactus safe for cats too?

Yes. The ASPCA lists Christmas Cactus as non-toxic to cats as well as dogs and horses. As with dogs, a cat that eats a lot of the plant may have brief stomach upset from the fiber, but no true toxicity is expected.
