Its a chinese evergreen, _Aglaonema_ sp., probably A. domesticum. Not really recommended for animal habitats where there a grazing inhabitant. Not super toxic though.
Its in the Aroid family, and like most in that family, is has special oxalates called raphides which cause an immediate burning sensation when bitten into. Most animals take one bite and never try it again. A small number might eat enough to hurt themselves. Your call.
