Hey I have two female mice who have never been with a male. But one of my mice seems to be going crazy.
She's chewing everything (house, tunnel , steel wheel, food container) and she also seems to be nesting; she'll collect all the sawdust and puts it in the house, by either digging or picking it up in her mouth.
The other mouse just seems to be very chill and runs a lot.

Is this normal?

Hi Jess,

Yes, "redecorating" is a completely normal behavior. Doing it suddenly could mean nesting, but it could also mean stress, a change in temperature, a weird new smell, or even just boredom. You can try adding different hides or toys to mix it up a bit, if you wanted to see if that makes much of a difference, but it's really a very normal behavior. :)

I can answer questions regarding mice as pets, mouse behavior, color and coat genetics, breeding techniques, and general health questions. I can help with caging and setup, nutrition, social issues, and what to do in most mouse emergencies (such as unplanned litters, injuries, fighting, etc.). I can also assist with questions pertaining to orphaned mouse pups, weaning litters, and questions of mating and birthing. I cannot answer questions about exotic or wild varieties of mice such as spiny or pygmy mice. *****FOR EMERGENCIES, anything requiring immediate medical intervention, PLEASE take your mouse to a professional veterinarian or wildlife rehabilitator who works with mice as soon as possible!

I have enjoyed the companionship of mice nonstop since 2004, and spent a year caring for them in a lab where I learned a great deal about their breeding, social needs, and health. I spent a few years breeding them, specifically working with albinos, marked mice, angora mice, and satins. My education never stopped - I am learning something new every day from current and well-established research thanks to the wonderful folks at the Jackson Laboratory, as well as from my wonderful mousey friends online. I also love learning from my terrific questioners here on AllExperts - you folks keep my passion for these amazing animals alive and well!
