Question: are plumeria plants poisonous to cats?
Answer: BRIEF: Is Plumeria rubra poisonous to cats? ... The sap from Plumeria rubra is known to cause dermatitis (skin irritation) and I don't know for sure, but since it is in the dogbane family it might well contain some cardiac glucosides (like oleander, dogbane and foxglove) that would cause problems if eaten.
