Monsteras are relatively low maintenance, making them an attractive addition to any home. Unfortunately, they also contain insoluble calcium oxalates making them highly toxic to cats. Symptoms include burning of the lips and mouth, excessive drooling, oral swelling, and vomiting.  

Jade Plant (Money Plant)  

A succulent which is supposed bring fortune and good luck to their owners – unfortunately they are not so lucky for cats. They are highly toxic causing symptoms such as vomiting, lethargy, depression, and incoordination if ingested.

Easter Lily

Eating small amounts of any part of this plant can lead to a cat's death from kidney failure if not treated by a vet within 18 hours. One to keep out of the house.
