This story does not have an amazing ending! Ahhhh! The picture of that poor baby fledgling is haunting me and I just sat down to eat breakfast and now I have lost my appetite, darn you! Lol, the dogs get my cereal.
Anyway, poor fledgling. It is too bad, this time of year when the baby birds leave their nests, or accidentally get pushed out by us, they are attacked by predators, mainly dogs and cats. My dogs have killed their fair share of animals and it breaks my heart, not much we can do to stop it, and I have tried everything, though they have stopped killing birds and I keep my cats indoors during this time of year when the fledglings are on the ground and are the most vulnerable (cats are considered an invasive species, killing over 20 million birds a year, cats were introduced to North America and birds have not evolved a way to escape from their claws when they swipe). I rehab ill, injured, and orphaned wildlife, mainly birds, so you can imagine my horror when my own animals kill one :-(
Anyway, about your chameleon and your superhero powers

, not many people get a chance to do that on a chameleon! I did CPR on a Dwarf Shield-Tailed agama (Xenagama Taylori) and she was dying of dehydration and emaciation and so I gave her fluids, electrolytes, to try to revive her, and the electrolyte polarity of the solution compared to her body was off, therefore causing her heart to stop! (if you shine a flashlight through their backs towards you up by their throats, you can usually see their beating heart), So I pumped her arms in and out from the side, which not only pumps the heart, but creates positive and negative pressure in the lungs so you don't have to practically stick their head in your mouth to breathe for them, then after about a minute, she took a breath, and came back to life. If she could have only told her side of her near death experience, same with your cham!
