Christmas cactus is generally considered non-toxic to cats, but it can still cause mild stomach upset if chewed or eaten.

Toxicity level

Most veterinary and pet-safety sources list Christmas cactus (Schlumbergera species) as non-toxic or low-toxicity for cats, meaning it does not contain the dangerous compounds found in plants like lilies or mistletoe. This makes it one of the safer holiday plants to have in a home with cats, as serious poisoning is not expected from small nibbles.

Possible symptoms

If a cat eats part of a Christmas cactus, the fibrous plant material can irritate the digestive tract. Cats may show mild, usually short-lived signs such as vomiting, soft stool or diarrhea, slight lethargy, or reduced appetite.

Hidden risks

While the plant tissue itself is not considered highly toxic, products used on or around the plant can be more concerning. Fertilizers, pesticides, or leaf- shine sprays that are not pet-safe may be harmful if a cat ingests treated plant parts or soil.

Safety tips

To reduce risk, it helps to place the plant where your cat cannot easily reach it, such as on high shelves or in hanging baskets. Use only pet-safe fertilizers and pest controls, and promptly remove any broken or fallen pieces of the plant.

When to call the vet

Contact a veterinarian or a pet poison helpline if your cat eats a large amount of Christmas cactus or shows persistent vomiting, repeated diarrhea, marked lethargy, or refusal to eat. Even though serious toxicity is unlikely, a professional can advise whether your cat needs an exam or treatment based on the amount eaten and symptoms.
