Good news. While I was taking my dog, Scout, outside, Nubbers just walked up to my stoop like nothing was wrong. I am so incredibly relieved he is okay and back to me but also incredibly pissed that he gave me several nights of anxiety in the first place. Let me tell ya, I am never gonna let him near open windows unsupervised ever again, screened or not.

Thanks to everyone for your concern and help. I'll let you know if he gets back out again but for right now I am gonna see about getting a few cuddle sessions in with my little baby boy. :)
