Is Christmas Cactus toxic to dogs?

Christmas cactus is non-toxic to dogs (S0 Safe): the ASPCA lists Schlumbergera bridgesii as safe for dogs, cats, and horses, though Pet Poison Helpline notes that eating it can cause mild GI upset such as vomiting or diarrhea.

FAQ

My dog ate part of a Christmas cactus — is this an emergency?

No toxin is on record, so this is not an emergency. The ASPCA lists Christmas cactus (Schlumbergera bridgesii) as "Non-Toxic to Dogs, Non-Toxic to Cats, Non-Toxic to Horses." Pet Poison Helpline adds a practical note: "Even though this plant is considered to be non-toxic to pets, ingestion can cause mild GI distress (vomiting, diarrhea)." It also says "some cases of GI distress could require veterinary treatment," so if vomiting or diarrhea persists or gets worse, call your vet.

Does this verdict cover an Easter cactus or a Thanksgiving cactus?

Partly. The ASPCA's Christmas Cactus entry gives Easter Cactus as another name for the same record (Schlumbergera bridgesii), so a plant sold under either name with that scientific name on the tag falls under this S0 verdict. The ASPCA has no entry under the name Thanksgiving cactus, so we do not extend the verdict to a plant sold that way unless its tag says Schlumbergera bridgesii. If the tag is missing, ask the seller for the scientific name, or ask your vet before assuming.

My cat ate a Christmas cactus segment — should I worry?

No emergency. The ASPCA lists Christmas cactus (Schlumbergera bridgesii) as "Non-Toxic to Cats" — no toxic principle is on record. There is no separate Pet Poison Helpline entry to add to that. Skip the panic, and call your vet only if vomiting persists or worsens.

Are the flowers and buds safe too?

The ASPCA's non-toxic listing covers the plant without singling out any dangerous part — no toxic principles are listed at all. Neither ASPCA nor Pet Poison Helpline flags the blooms separately. Dropped buds are the most tempting cat toys in December; if a few get eaten, watch for nothing more than the mild stomach upset PPH describes, and enjoy the rest of the bloom.
