It appears that Plumeria sap and bark can be irritating to the skin, or mouth, and may cause digestive issues, such as diarrhea or vomiting, if swallowed. From what we could find, it is not highly toxic to cats, but in certain situations (amount eaten, cat age and health, etc.) its effects may mean that a cat needs to be taken to the vets for help. It would be best to keep it away from cats or other pets, as well as children.
