Please post a clear photo of the plant and it's stems, leaves, and whatever structures you have available, laid out on a flat surface, so we can be sure.
Several aroid genera look alike and we need to see a clearer photo.
At any rate, ALL aroids, including the oft recomended pothos, contain high levels of oxalates, which is the "toxic" action of the plant. While some have high enough oxalates to pose a threat of stomach upset and general malaise, I don't consider them toxic, but recommend watching and in the case of philodendrons and monsteras, remove the plants, of the chameleon takes more than an occasional nibble.
