Pretty Boy ran to me with the squirrel in his mouth and all the while, the squirrel was squealing in fear (and perhaps pain). Pretty Boy then put the squirrel down, where it lay, squealing still. And then it quieted. And then Pretty Boy played with it, but the squirrel wasn't having fun.
Eventually, I got Pretty Boy away from the poor squirrel and Joe picked up the squirrel and took him back to the giant sycamore where MaMa squirrel had been yelling incessantly the entire time. After about 15 minutes, the poor scared, and maybe slightly injured, squirrel made his way up to the lowest of the giant branches, where he rested while MaMa continued to call him back up to the nest in the hollow in the tree.
Hopefully, the squirrels are all happily cuddled in their nest tonight.
