not sure what it is by name, but i know its not toxic. i've got one in a pot with a ficus and draceanea. Kiwi loves plants, and has never shown interest to this one. so i wouldnt worry about it either. it does create good bottom foilage though.
I can also concur that it is of the genus Syngonium. They have thin leaves, grow fast, and are easy to propagate. I am glad for you that it is not a harmful plant to the chamy because it would be an excellent choice to have in an enclosure.
I had one of these in my Veileds cage when he was young. He loved it. Slept on it every night and always climbed down towards it for a look around. No idea of its name, we called it "the gay plant" because of its pink flowers and because he loved it so much. Pretty sure they are Cham-safe. We had no problems with it.
