its just ivy, but a indoor breed. if you are from the northeast, a lot of this ivy grows wild and its really dark brown looking instead of blotched. from my experience with the plant, it shouldn't be a problem.
This is and Ivy something like English Ivy I don’t recall exactly.
Apparently Ivy can be toxic and it has been suggested not to use it here on this forum by some.
That said from what I was able to research is that some varieties of this can flower and the Flowers are very toxic even to people. But have to be consumed in large quantities, although nobody will say what that is.
Anyway Veiled’s seem to like to eat Greens from what I have read here but Panthers not so much.
I have it in my cage with a juvenile panther and it has no interest in it other than a place to hide and Sleep so if you use it keep an eye on your Cham.
