Rexy is found!! We have a sunroom type enclosed porch attached to our house and that's where she was living for EIGHT days!!
Each night I set up her heat lamp and put out food, but nothing. No wonder! She was on the porch. So this afternoon when I was out there watering the plants, there she was lying in the sun on top of the watering can. Her little head tilted looking up at me as if to say, "Where have you been? It's been freezing out here!" I screamed in shock and then cried with happiness. This morning when I woke up I said the longest prayer for her to be found today. Prayer really works! I can't beleive she was out there at night. Last week it got down to 30 degrees in the night. Poor little girl! I feel horrible. But she's back in her home all feed and warm. Next time I'll keep a better eye on her when it's exercise time. Thank you all for your suggestions and support. I had my husband rip the refrigerator out of the wall this morning because I was positive she was behind it (only because that's where Skitz was hiding and I was so desperate). Yea! Rexy's back! I'm so happy right now!
