My Sanke escaped in My Basement where do I look?

Where you should look depends on how your basement is set up? Is it a finished basment, or one of those basements where you can see all those poles, vents, and rafters everywhere, and there's no carpet?

Just when you absolutely lose any and all hope, that is when you'll find her. Happened to me 3 times.

Hey, she might be in the ceiling. My first BP got out, and she was found in the rafters of the basement ceiling (sadly it was winter, and she was found dead.)
If there's any way you can, could you look in the ceiling? Maybe she slid up into a panel.
If your climate is not too cold, though, chances are she's alive and well in some dark crevice of the basement.

Thanks to everyone who helped me with my search, it took me a while to to reply, but I found my precious, lol, inside my furnace. She was cold and lethargic. Thank god she was alive, it would have been a close call if I'd find her at a later date. I found her over the weekend, I wasn't going to give up looking through my 2500 square foot basement uless I found her, she was only about 10 feet away from her cage.

She is doing well now, she ate 3 large mice sinse. At first I was worried because she had dirt over her snout and when I tried soaking her to wash it off, she started opening her mouth and showing typical signs of RI. Now that she has eaten, she should be ok. Im now trying to organize my bedroom so that I can put her setup back in to prevent an insident like this again.

Thanks to everyone with all your help and support. Dave.

Oh one more thing, she was found inside my furnace where the fan blows the hot air through the ventilation system. There was no way she could have crawled in there unless she went through the ventilation system. Let just say that she must have had a few busy nights before crawling into the furnace. Im just glad I finally found her.

really glad to hear that you found her! Keep a close on her & make sure she is doing well. Hopefully all is right with her world! you must be SO relieved!!

I am very glad that you found her! And what a place to find her, too. I hope you are able to get her enclosure secured well enough to prevent future escapes. All's well that ends well.

Excellent news! I'm always thrilled to hear of a lost&found pet! If I were you, I would keep her a little warmer and the air a little more humid than usual. Doing so could help curb a threatening RI before you even know she has it.
