Carole ~ How about another friendly phone call? Leave a message if they are not in. Invite them to join pet talk and tell them that some crazy lady in Alaska was asking about their new baby and you just wanted to pass on the info. Re-state that if it doesn't work out for any reason, you will gladly take him back. Sometimes it just doesn't work out and if he's not adjusting well (peeing, etc. -- make it sound like he could be the problem, not her kids) that you would be happy to find them another kitty.

Worth a try?
