Holding and Immobilizing Chameleon Safely. (For Him and for You)
How to grab a grumpy chameleon so that it does not bite you?
Put the back just behind the head between your thumb and index while the dorsal crest is touching your skin between these two fingers. Hold fimly but gently. Handle quickly. It is stressful, so do it only if needed and be as respectful and quick as possible. Do not panic, just hold. It can be painful if he grabs your fingers with nails. It is less painful and less damage than being bitten by the powerful jaws.
Anyway, remember, the animals is about 1000times (and more) smaller than you in most of the kept specimens.
