- Thanksgiving cactus: pointed, claw-like teeth along the edges. Usually blooms around Thanksgiving.
- Christmas cactus: smooth, rounded, scalloped edges. Usually blooms closer to Christmas.

Holiday cacti are generally considered safe for cats and dogs; the ASPCA lists the Christmas and Easter cacti as non-toxic.
