It's a bat! A really sick one, at that. It was outside the entrance to my gym. Thinking I'd be helpful in case, y'know, the bat was rabid or just needed to be put down, I told the people at the front desk about it.
"Oh! He's still there, huh? He was there yesterday, too!" was the response I got.
Um, yeah, he's still there...dying of fright or white nose disease or rabies.
By the time I got done pumping iron and doing one pullup(!) they had done something with the poor little critter. I hope he's either free and healthy or out of his misery.
