Isn't it helpful to know that you may be underfeeding your pets? The mice are probably too small, switching over to rats will help. It's relevant how you are feeding your other animals though because if one is being underfed, it's likely that the others are too.
I didn't see your answer for what you are using to regulate your heating with. If you are not using a thermostat, please unplug your UTH immediately otherwise your snake could get badly burned.
No need to blow up, questions need to be asked in order for everyone to understand if there is a problem with your husbandry.
