Severity: Mild
If a Christmas cactus showed up in your house sometime in November, there's a good chance it isn't actually a Christmas cactus. American retailers sell three closely related holiday cacti - Thanksgiving, Christmas, and Easter cactus - under overlapping names, and what's commonly sold in the fall is very often true Thanksgiving cactus (Schlumbergera truncata), forced into bloom on a retail schedule. University extension sources note you can tell them apart by the flat, leaf-like stem segments: Thanksgiving cactus has pointed, saw-toothed edges, true Christmas cactus (Schlumbergera x buckleyi) has softer, rounded, scalloped edges, and Easter cactus blooms in spring rather than winter.
Here's the good news: it doesn't matter much which one you have. ASPCA's plant-database entry for Christmas cactus (Schlumbergera bridgesii) lists it as non-toxic to both cats and dogs, and its Thanksgiving- and Easter-blooming relatives are closely related, thornless epiphytic cacti with no toxic principle reported for any of them. At most, a pet that eats a large quantity might get mild, self-limiting stomach upset from fiber and texture, not poison. Of the plants that show up in American homes every winter, this is one you genuinely don't need to lose sleep over.
