cats if watching the chameleon may stress it out but the cham should get used to it chams also don't hear much, just don't pump bass, I think chameleons auditory level starts below the human voice tho. as long as the cat cannot attack the cham u should be fine I hope the person who doesn't approve of the chameleon changes their mind, chams are amazing creatures sometimes people just don't see it
Update: Heard back from Fabian Aguirre, who seems to be familiar to some folks around here, that the project is on-going and he's not sure when he'll be done with a long form. Just the 15 sec clip on this link, tho, is fantastic. Chameleons are such amazing lifeforms, and to see them behaving in "normal", "natural" ways is fascinating. And then add to that, behaviors conducted at such a small scale. Or...I don't know what it is, but there is a special charm to pygmy chameleons.
