We often see bats flitting around at dusk, especially when the sky is clear and there is little wind, but we've never seen one up close and motionless. Unfortunately we discovered a dead bat on our patio this morning, with some sort of injury on its back. One of our cats might have been the culprit, but I fail to see how they'd have managed to do it. Bats are exceptionally agile, and should easily be able to evade the clutches of even the most determined feline.
