Sounds like it might have gotten itself home if someone hadn’t scooped it off the street and taken it to a shelter.
As someone noted, at least it managed to avoid Springfield.
My 3 dogs and 1 cat are all chipped. However, you could not run them away even if you tried. Oddly, the cat is the boss and the dogs let her have her way with them. The only time they get into an argument is if both want to lay on me at the same time.
