is christmas cactus poisonous for cats

Yes, Christmas cactus can be poisonous for cats. The leaves and flowers contain oxalic acid, which can cause irritation to the mouth and stomach. If your cat ingests any part of the cactus, they may experience drooling, vomiting, diarrhea, and other digestive issues. In extreme cases, it can even cause organ damage. It's best to keep Christmas cactuses out of reach of pets, and if you suspect your cat has ingested some, contact your veterinarian immediately.
