4/5: UPDATE FOUND! Patches was found in Middleton, 8 miles from where he went missing(!), and brought to a vet for a chip check. The vet called and Patches came home this afternoon. Thank you to all who have been getting the word out and helping to locate Patches! I really appreciate it. If you have cross-posted screen grabs (vs this link) to another site, please update to show he is found. And thanks for cross-posting!
