are christmas cactus plants poisonous to cats

No, Christmas cactus plants are not poisonous to cats. In fact, they are relatively non-toxic and unlikely to cause any significant health issues for cats if eaten. However, it is still best to keep them out of reach of curious pets and prevent them from chewing on the plant. Cats may experience minor stomach upset if they consume a small amount, but it is unlikely to be serious. If you are concerned about your cat's safety or notice any signs of distress, please consult a veterinarian immediately.
