Still searching, no luck. Yes, we have taken many, many hours and looked in every room, went as far as re-arranging EVERYTHING, taking everything out of the closets and looking into everything, then putting it all back. Even took every piece of clothing and searched, then refolded them. The house is so clean, it's scary! These are our babies, so we have not taken this very lightly. The good news is, no bad smells, so he must be alive.
We've always let our beardies out, never thinking they'd get lost, because I always kept an eye on them. Now, the long colored string is a great idea and when we find Skitz, he's getting a BRIGHT PINK ONE. lol The female, well, since Skitz has been gone, she hardly eats. She may not have loved the little guy, but she liked him enough to do the dragon dance.
Still keeping the house warm. I'm thinking the electric bill has gone up 150.00 in the past 1.5 weeks. Thanks for all of the replies. The feedback is amazing and I'm going out to the garage to make him a HOT PINK LEASH.
