Mice/Death of mouse


My mouse literly just died in my hand , it lookalike she couldn't breathe and started twitching and her. Eyes whent from red to black over the last two days . But now I'm worried about my other mouse as she has 5 babies and the one that passed was her best  friend and I know that they love company I'm worried she will get lonely should I get another mouse or put dad back in the cage she is already searching for her friend .

Hi Alana,

I am so sorry for your loss.  I know that must have been very difficult and scary.

If any of the babies are female, you can consider keeping one or two girl babies with her as company.  If you decide to get her a new mouse friend, however, I would wait until all of her pups are grown and left the cage, then follow normal quarantine precautions for the first three weeks (keeping the new mouse in a separate cage away from the others) to prevent a new mouse from bringing in any illnesses that could affect your survivor.  If she is grieving, this could lower her immune system, so you'd want to be extra careful.

Unless you are breeding them again, dad should not be put back in the cage.  Not only would he be a risk to the pups, but having a male in the cage is typically very stressful for the female.  She'd also be at risk of becoming pregnant again, which can happen immediately once she has her pups and then again every five days or so as per her normal cycle.  Back to back pregnancies can be very harmful to the momma's health.

Right now, she's probably going to be focusing on her babies.  If the pups are old enough to be wandering around on their own, you can try giving her a little extra attention yourself to help her cope.  Once the babies are all old enough to fend for themselves you can decide if she needs a friend, or just some more time with you.

Best of luck, and I'm so sorry again for your loss,

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!
