Hi Charlotte,
Mice usually are jumpy/twitchy but without seeing your mouse, it’s hard to say what is going on. It could just be a normal mouse moving.
If she’s eating and drinking she is probably fine. YES, mice , all mice make nests, usually quite large one’s too. Add some paper towel or toilet paper tubes and she will have a ball shredding them up. Sounds like she may be pregnant. If she is, you will soon find baby mice! They are only pregnant for a few weeks before having babies and they can have around 7-14 babies.
Enjoy your new mouse!

There are ups and downs. there are days he’s doing good but other times he’s really sick. We would never give up, we love him. Do you have any idea about the signs of recovery? like the hardening of his pad foot?
Thanks for the reply. we’ve been regretting about not having enough thought of giving him vaccines. Thanks again, best of luck!
