You do not want flying squirrels.
I had a bunch living in my attic (many years ago). Their urine is red (my house had red lines coming down from the eaves). Yes, like some sort of Wes Craven horror film 😱. They were humanely purged and I have sealed even the tiniest of crevices that they might return to. Truly a nightmare.
