Jax Ville, your instincts are good -- if Bubbles is comfortable and confident in the territory he may need some extra help getting home. Thoroughly search using a flashlight during the day and especially at dusk (when it's dark and quiet) to determine whether he’s ill or injured and hiding nearby, or stuck somewhere. Check every crack and crevice, look in outbuildings, containers, vehicles, under foundations, sheds and porches, into trees, etc. — call and listen carefully for Bubbles’ cries (he may alert you to his location). And it’s important to ask neighbors to do the same and make sure Bubbles didn’t hide and become trapped in a shed or garage, etc.
