Logan - this might be hard to do, but I did it years ago when a cat of mine went missing (I did find him, alive and well, trapped in a cottage basement - the cottage was for sale, had been shown to people, and he got in...I broke in through the basement!).

I called the highways/roads people to ask if they had found a dead cat. I was at the point I just wanted an answer.

HUGS and I hope you have news soon - and good news.
