We have three firebellies that have been croaking as of lately. This morning, all three were in separate corners of their cage, stiff and very cold to the touch. The cage is kept in our bedroom so the temp would be around 70. They don't have a dried up and shriveled look nor do they smell dead. They are in a rigid upright postition. They are two years old. Is this a common thing for them to be hibernating? How can I tell if they are dead vs. hibernating? Thanks!
