Is Dipladenia (Mandevilla) toxic to cats?
Mandevilla spp.
Mildly. The ASPCA lists dipladenia (mandevilla) as mildly toxic to cats — a chewing cat typically gets mouth irritation, drooling, and vomiting rather than a medical emergency, but it is still best kept out of reach. This classification follows the ASPCA Toxic and Non-Toxic Plant List. The ASPCA does not individually list Mandevilla or Dipladenia on either its toxic or non-toxic plant database, so a non-toxic claim cannot be made. It belongs to the dogbane family (Apocynaceae), which includes toxic relatives such as oleander, and the RHS notes it "may cause mild stomach upset if eaten" with sap that "may cause skin irritation." Ingestion can cause drooling, vomiting or diarrhoea in cats and dogs; the milky sap can cause contact dermatitis. Keep out of reach of pets and children, wear gloves when pruning, and contact your vet or the ASPCA Animal Poison Control Center (888-426-4435) if a pet eats any part.
