Every year wildlife rehabs are delivered many perfectly healthy baby possums for this exact reason and generally, it means they get a little boost of assured safety, food, and hydration before being released. Imagine, you're newly 18 and starting your adult life - you're just kind of walking around, maybe on your way to community college or something, and a Kindly Cosmic Horror picks you up, carries you to a fancy hotel where you are given several really excellent meals and maybe receive a series of vaccinations, then you are dropped into a resource-rich area approximately nearby where the first Kindly Cosmic Horror picked you up. This is how life is for young Virginia possums every spring.
