So sorry that your family is having to endure this worrisome time. There is someone who might be able to help you. Her name is Hilary Renaissance. She is a professional animal communicator. Her website is: calmpet.com. Phone Number: 206-782-7815. I attended a class taught by her 11 years ago. I feel certain that you have already contacted local animal shelters and posted flyers. Also local veterinarians? Are there any low lying bushes in your neighborhood? Your little MimiGirl might be frightened and hiding somewhere nearby, not knowing what to do. My heart goes out to you and your family.
