When a pet gets zapped and LOSES points in level of defense or strength, it should not say (-) before the number. "Your pet gains 2 levels" and "your pet loses -2 levels" means the same thing. If a pet loses points in a level or defense (etc) it should just say loses or lost.
I am going to move it over to content issues since this is not a problem with the actual zapper but the wording.
This should be a quick fix maybe?
