Is a Christmas cactus safe for cats and dogs?
Schlumbergera buckleyi · Cacti
Non-toxic to cats and dogs
Confirmed at genus level for Schlumbergera. Almost nothing else on the December gift shelf comes back clear, which is the whole argument for this one.

Safe, and usefully so in December. Schlumbergera buckleyi appears on the ASPCA's non-toxic list for cats and dogs, which is more than can be said for most of what arrives in a gift bag that month. Poinsettia is on the toxic list with mild effects. Cyclamen and florist azalea are both recorded as severe, and amaryllis moderate. A Christmas cactus is the plant you can accept from a relative without moving it to a high shelf the moment they leave.
Worth knowing anyway
Safe to have around animals, though not safe to graze on. Unlike most cacti it carries no spines worth worrying about, so what you get is mess rather than injury: the segments snap off cleanly when a cat swipes at the plant, and a dog finds them on the floor before you do. Some animals are sick after eating a few and others are not. If it keeps happening, ring your vet.
Living with one
This is a jungle cactus, so it behaves nothing like the succulents it gets shelved with. It takes bright, indirect light, and the catalogue keeps it on a steady schedule of around every eight days all year rather than drying it out through winter. It can live on the low table where you would not risk a poinsettia. Just leave it there, since moving a budding plant around the house is the usual reason the flowers drop before they open.

Questions people actually ask
Is a Thanksgiving cactus the same as a Christmas cactus?
For safety purposes, yes. Thanksgiving cactus, holiday cactus and crab cactus are all names attached to Schlumbergera, and the catalogue treats them as one plant, so the answer for cats and dogs does not change with the label on the pot. Growers do sell slightly different plants under those names and the segment edges give it away, but that difference is horticultural rather than a safety matter.
Why did my Christmas cactus drop its buds before flowering?
Usually because something changed while it was setting them. A cactus in bud objects to being moved, to a draught from an opened door and to a swing between bone dry and soaked. The catalogue keeps it on a steady interval of around every eight days year round rather than a winter dry spell, and puts it in a cool room between 15C and 24C at 50 to 70 per cent humidity. Buds already dropped will not come back.
Which Christmas plants should I keep out of the house instead?
The dangerous end of the December shelf is cyclamen and florist azalea, both recorded as severe for cats and dogs. Amaryllis is moderate, poinsettia and the Norfolk Island pine sold as a living Christmas tree are both mild, and true lilies are severe for cats. None of that means a Christmas cactus needs guarding, which is the point of choosing one.
Can someone plant-sitting over the holidays see the schedule?
Yes. A household syncs over iCloud, and a sitter can be handed a link before you travel so the watering does not stall while you are away. Anything logged while you are gone feeds back into the schedule rather than sitting outside it, and the care history can be exported later if a vet ever asks for it. A plant in bud is exactly the one a stand-in tends to get wrong.
