Any mice owners out there? I need some help/advice on a few things…
First, an introduction. I own three females; Whitney, Sierra and Lassen. To my knowledge, Whitney and Sierra are litter mates, whereas Lassen is not. I know that is generally a bad idea, but the girlfriend read online that females are best in groups of three, and that’s all she wrote. Lassen was bought from a different store, at a different time.
The broken chocolate hiding deep in my pocket (you can only see her face) is Whitney. She’s the shyest of the group, although that’s not always how she’s been. More on that later. She’s the biggest of the three.
The broken blue is Sierra. She is by far the most sociable. She’s a gem of a mouse. She’s active, alert, and curious. She’ll run to the side of the cage whenever I walk in the room. She’ll climb into my hand and she’ll eat from my hand. She loves the wheel, loves the ball, and loves running around on the bed.
The black one in the foreground is Lassen. She’s relatively small compared to the other two. She also used to be the shyest. I would go days at a time without seeing her. She’s a lot better nowadays.
Anyway, on to my questions:
1. Whitney, she used to be the most sociable of the group. I don’t know what changed, but now she’s not. She spends all day in the house, has gained weight, and won’t even come out for her favorite treats. Anyone know what may have caused the demeanor change?
