Oh no Jeanne, I'm soo sorry.
Any sightings of him yet???
Like everyone else is saying..set up his cage outside with his favs. Keep calling him. I'm SURE he knows your voice very well, so maybe make a recording of it so you can play it over and over? I'm pretty sure you can't be right there calling him every minute so maybe a recording??
Alert all your neighbors and have them pass it on to their friends. Putting up lost posters might help too....afterall, look how many keets have been found by others lately!!
I hope with all my heart you get him back safe and sound. Can't imagine the heartbreak and worry you're going thru
Call animal shelters and vets in your area? Ya never know.
Hang in their girlie (((Hugs)))
