The toxic principle is soluble calcium oxalates, most concentrated in the underground parts, including the swollen caudex base of this species. Signs are vomiting and oral irritation/salivation in cats and dogs, with kidney failure possible in grazing animals. Signs usually appear soon after chewing rather than hours later — watch for drooling, pawing at the mouth, vomiting, loss of appetite, or unusual lethargy after your cat has had access to begonia partita.

Stay calm. Remove any plant from your cat's mouth and take the plant away. Note how much was eaten and when, and do not induce vomiting unless told to. Call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 and follow their advice; a leaf or photo helps the vet treat it correctly.
