I checked with them before I went to the Vet's office. I spent a good part of the day phoning all the pet store chains too.
I have a candy thermometer to keep track of the food. It's usually between 102 and 105 degrees when I feed. He still hates it
I ended up buying a heating lamp and shone it on the bottom of the cage... Christmas started whining like mad, then mom and dad filled him up to keep him quiet
Maybe he just needed more heat.
