I started my colony of Blaptica Dubias yesterday. I was curious if at anytime or the shell of the dubia harmful when feeding or are they safe to feed at any stage of their growth.
Well, a chameleon can become impacted from eating anything that has a "shell" but they also need it. And remember, they are only as nutritious as what you feed them. (So cat and dog food is not a good idea even if you plan to gutload before feeding.)
