The bat was also cold - torpid. We had a go at cleaning its wing up, and it got a lot warmer from him holding it, so he tried to let it go in the back yard. Hmm - still too cold. Flutter flutter flutter thunk - down to the ground. Tried that a few more times then he took it home to get it a bit cleaner and warmer.
Weather looks like it's turning back into summer again at last.
Minute, live, undamaged by the cats, but had an injured wing with a big slug crawling on it. It was squeaking like nobody's business, moving, not bleeding. Apparently you need a license to do things with bats. Some hoverfly-encouraging plants would be good too. Over the weekend I tried, tried and tried again to drill holes in the wall to put up vine eyes.
