Well, as far as I know she was healthy. She was about 2, this was going to be her first litter with us. Rex, normal size, gestation was coming along fine. She wasn't supposed to deliver until next Wednesday, at the earliest, but being her first litter, I gave her the box early and a pile of bermuda to fill it with. I did that last night. She sniffed around the box and the bermuda, and then I left her. This AM, I found her laying on the bermuda, on her side, when I opened the hutch, I saw the malformed kits and some blobs. All were dead. She was still slightly warm. Any ideas what may have happened?
