I live in Waco and order from Big Cheese once a month or so. I got 275 live mice last time and they are all fat and healthy. They give you a few extra just in case one gets overheated in transport and dies(it happens.. It IS Texas). Their live prices are the same as their frozen prices. I have ordered frozen from them before and they are all well-fleshed, clean, lined up neatly on the meat trays, and vacuum-packed. They don't smell either when thawed.
Oh! And Big Cheese also sells rabbits, but they aren't on the site. They are $2.25/lb regardless of what size. They come individually wrapped and vacuum-packed. They are always very good sized, healthy, clean, and don't smell whatsoever when you thaw them out. My boa Sonja loves them.
