My whites tree frog climbed into a small cardboard box while I was trying to feed him crickets and he got stuck. It took a lot of effort to dislodge him and him made a shocking croaking noise, I felt really bad but I could not leave him in there. Two days later he has red abrasions on his legs and belly, at first I thought it was red leg but it appeared literally overnight. Is it possible the cardboard box caused the redness?
