This is a wild shot but have you ever heard of Nextdoor.com? It's a "private social network for your neighborhood". You join using your address and get to see posts from others in your area. We use it to keep up with the goings on in the neighborhood, curb alerts for discarded treasures, get togethers, placing things for sale, pet rescues, suspicious persons...all kinds of stuff. It's safe and no ads. Maybe state your dilemma as you did here and you might get some good feedback or even find them a new home! Good luck!
