I must say I was a lil sad when he didn't appear in April as I was told he would. I figured he had found a way out. We have only had 1-3 bats around outside at night-most of the time I just see the one. my lil buddy. At 3am I hear the mice running around again but it sounds like they are trying to get into the gouldians cage. So the light comes on. There is Bruce flying around-taking a break on the cage. Casey could care less-even if he's flying within her grasp. She goes back to sleep. He takes his lil spot in the corner where I thought he would stay-nope-he decides he needs a new spot. between the floor boards above. I went back to bed with my lil super hero watching from above.
