What do you do if you find an injured bat on the ground? Don't touch it! Their cuteness doesn't exclude them from transferable diseases. It may be stunned from hitting a window so wait a little to see if it moves, and if you think it's really injured, it's time to call some professionals!
There's so many bat rehabilitation and refuges around. You can find one local to you on a map compiled by @batworldsanctuary.
The pattern shown is called Catching Bats, which is currently on sale, along with all my other bat patterns on etsy!
