I am syringe feeding a chameleon that doesn't want to open its mouth. As of now I am gently opening his mouth and placing the syringe round around his teeth and then pushing the food into his mouth. Should be trying to go into his throat with the syringe? Should it be a rubber tipped syringe? Right now it's a hard plastic tip. The experience is traumatizing for both of us so I would like to make this the least invasive as possible.
