Chameleon

I saw this in a garden centre along with some smaller examples. I find Chameleons fascinating in the extreme, I could watch them endlessly. Same with any kind of reptile, it stems from when I was the Newt monitor in junior school I think. Anyway, to my point, although I think they are wonderful creatures I feel very guilty when looking at them (and enjoying them) in this environment. They should not be kept in a tiny glass room. It's a genuinely uncomfortable feeling that I get which I don't experience in any other situation. Beautiful but shouldn't be a 'pet' for somebody, yet secretly (not now!) I'd love one as a pet. Help!!!
