I believe chameleons can sense one another. This was my experience when I had my three. But it may be that Karma is annoyed with the new divider and not at all that he can sense Kensho.Question for ya'll...
Can karma and Kenshō smell eachother? Karma has been moving around his entire enclosure (which is not typical of his behavior). I have a divider between them and they can't see one another. If its bothering them, I can move Kenshō and give them both their own bedrooms.
