No action required. Only large amounts of the fibrous stems could cause mild mechanical stomach upset.

Common questions

My puppy eats the segments — is the soil the bigger issue?

Possibly. Fertilizer granules and soil in quantity cause more trouble than the plant. Use pet-safe fertilizer and cover the pot surface.

Is a true desert cactus different?

Desert cacti are generally non-toxic too, but their spines are a physical injury risk. The spineless Christmas cactus avoids that hazard entirely.
