dead bats - a sad sign of a buggy summer to come

I cleaned up 3 dead bats from the ice shelf still remaining on the back patio. Did the cats deliver them there, or did they hit the house in their desperate search for insects in the deep winter? Once again, the bats were afflicted with white nose syndrome. They awoke and flew out of their cave on Mount Aeolous when they only had enough stored in their bodies to sleep until spring. We've found 10 dead bats around the house as the snow and ice has receded to reveal their tiny bodies.
