I am extremely upset. I ordered a bags of rats and mice from rodent pro a while ago and everything has been fine feeding these rats and mice to my snakes. The rats where in perfect condition. On the other hand I had noticed on the mice that the hand or legs would sometimes be broken or completely gone. I figured this happened during shipping, I couldn't think of any other reason. Well today I was thawing a mouse for my small female and once it was almost done thawing the head was hanging off. It looks like someone cut right through the neck but the head is still attached. I was extremely disgusted and immediately put this mouse back in the freezer. WHY ON EARTH WOULD A MOUSE, KILLED BY CO2, HAVE ITS HEAD SEVERED??? On the rodent pro website it says they use CO2. Can I believe this? Has anyone else had any issues? I am going to contact them. If someone wants me to post pics I will but right now Im too disgusted to grab my camera.
