Well, I've got a serious escapee. Advice?

I know you said you want to just "mourn and move on"....but the "Mom" in me has to say, "Don't give up!" Actively searching may not work after a certain point...but I've heard SO many stories about missing snakes just popping up out of the blue days, weeks, even months later.

I had a friend who had a rosy boa escape. The snake was gone for two years. My friend moved into a new house. When he was unpacking one of the boxes out pops the rosy boa! A tad on the thin side, but hardly starving and none the worse for wear.

Good luck!!

A friend of mine had an escapee once, it went missing around his apartment for around 3 months.. then one day he was sitting in the living room, and it slid out from under the couch. Good luck!

Don't give up. Set a rat in a cage in the middle of the room on the floor. Heating pad with a towel and a hide on top of it next to the rat. Just leave it there. Most balls are found within a few feet of their cage, so I'd put in the room she was kept. As others have said, they will move towards heat so the trick is to make some heat where you can easily get to it.

We once took some snakes to my kid's school for a demonstration. When my wife got home, my Pied female was missing. We were not sure if it got out at the school, car or somewhere in between. It was February and I was sure she was lost. I almost tore the car apart looking. Then when my wive was driving one day over a month later, the snake dropped down on her feet. I put her back in her rack, fed her and she is a healthy snake today. I would not obsess over it, but keep an eye out and a trap set. Sooner or later you'll find out where she is.
