I want to thank all of you for participating in the quiz. I had a great time and hope you did too. All the answers were solid and logical. The mystery animal is one that we find commonly in caves and they exit to feed about the same time as the bats. The critter is a porcupine. Of course his shape and features are not obvious due to the thermal image. Thanks for playing, I will continue the quizzes. I just got back from a long week of driving and field work so I may not have anything up until tomorrow evening.
