Hi! Found a 1 wk old squirrel at the bottom of my pine tree. Tried to get momma to come get him, but after 3 days, no luck. No rehabbers in my area and F&G couldn't help me, so I'm fostering him. Very healthy squirrel: feeding well and no obvious health issues. He's closing in on 4 weeks and I just read that I should keep him over the winter season, is that true? I live in SE Idaho and our winters are very cold, so I want to make sure I care for him properly. If not, I would be releasing him mid-to-late November. Thanks for any/all recommendations~
