I have never fed a mantis enough that it looked beyond capacity, but when they are fat, I don't like to handle them alot.
Fat mantids can burst if they fall or jump.
Also, I have been squirted a few times. :mellow: If I am handling a fatty, I like to try to direct her abdomen away from me, because I don't like being squirted in the face. Sometimes I feel like they might be aiming at me.
