How to keep cats and dogs away from Christmas cactus

Christmas cactus have quickly become one of the best indoor plants, so it is a relief for pet owners to discover that the Christmas cactus is pet-friendly. ‘They are considered non-toxic, making them safe to keep around curious cats and dogs. However, the best practice is to keep houseplants out of reach of small children and curious pets just in case,’ says Eliza Blank of The Sill.

When living with pets, it is advisable to keep your houseplants off the floor and instead place them on a higher shelf, bookcase, or on a plant stand – we love this Bamworld design from Amazon. You could even pair them with cat-safe indoor plants for a botanical display. 

With Christmas cactus' tendency to drape gracefully over the sides of their pot, they are ideal for growing in hanging or raised containers – handy if you want to keep them well out of reach and nibble off mischievous pets. Just remember to position them in a bright or semi-shady spot, out of direct sunlight as this can scorch the fleshy leaves.

'The Christmas cactus prefers bright, indirect light,’ says Keira Kay, Bloom & Wild plant expert. ‘In a window with dappled light or a well-lit but semi-shaded location is best in order for this plant to thrive.'

It’s also worth knowing that the leaves of this plant tend to break off if knocked or brushed against, so another good reason to keep them up high on a shelf or in a hanging planter. However, should they get knocked off you can use these leaves to propagate a new Christmas cactus.

What do I do if my dog eats a Christmas cactus?

Like many succulents, Schlumbergera is non-toxic and perfectly safe to have around all household pets. The occasional curious nibble will not cause any discomfort, but as with all non-toxic plants, eating a large quantity of foliage can cause problems.

‘While Christmas cacti are not poisonous to dogs, they can cause stomach upset and vomiting,’ says Anirban Saha, founder of ‘If your dog does eat a Christmas cactus, watch for signs of an allergic reaction, loose stool, or an upset stomach. If these occur, contact your veterinarian immediately. As with any plant, it is always best to err on the side of caution.’
