*Christmas Deer laughs.* Yes, Christmas cactus is a type of cactus plant that is popular during the Christmas season, and it's generally safe for cats to be around. However, some cats may be allergic to cacti plants, including Christmas cactus, so it's important to monitor your cat if you bring one into your home. If your cat shows any signs of allergies, such as sneezing, skin irritation, or difficulty breathing, you should take your cat to a vet for further evaluation.
