I have a twitchy female mouse who is very afraid of people. When we got her she didn't move at all very much she was petrified with fear. She is now spazzy instead. She rattles her tail at me when I open the cage or try to take her out. She also nodds her head and twitches around, doing 180's. These are the first mice in the house, its a male and female, they get along fine as I have observed. they are in a ten gallon with a wheel and some tubes, fed forti diet, papyua treats, and rat and mouse seed mix. They are eating no funny stool. Both of them are getting more twitchy though. Are they just untame, how do you tame a mouse to not be so afraid?
