Mice/Baby deer mouse


Hi... I found a baby mouse only just opening eyes yesterday. It was suck in a glue trap and I rescued it... I have no Idea what to feed it... I have no puppy or and baby formula or goats milk. PLEASE HELP! I also cant get her to use the bathroom... I have been feeding it applesauce and oats, but I dont thik you are supposed to. Thanks :D

Hi Vanessa,

If it is old enough to be able to walk and move normally, oats are a good "starter" solid food.  You can also try commercial mouse foods, available at any pet shop.  However, if its eyes just opened, chances are it is going to NEED hydration from kitten or puppy formula.  You can buy time by offering stale bread that has been soaked in water, but this is not ideal.  If the mouse is indeed a baby, then it is mandatory that he or she get help with nutrition and hydration.

If you can't get puppy or kitten formula or mouse food, please try to find someone who can as soon as possible!  Mouse pups need to be fed every few hours, and the longer he or she goes without adequate nutrition, the less likely he or she will be to survive.  Try calling local wildlife rehabilitators that work with rodents, veterinarians, animal shelters and rescues, or even pet shops and local rodent breeders.  If you can find one who has experience with orphaned mice and who you can trust not to put the pup in danger, please consider letting them help.  He or she only needs formula until the pup can drink normally on its own, once it can, it can be safely released away from houses and somewhere with protection from flying predators.  Mice have very strong instincts, and by 4-6 weeks old they should be able to succeed in the wild.

The mouse pup also needs to be going to the bathroom almost every time you feed, if not every single time (not pooping each time is fine, but he or she should be urinating regularly).  I'm not sure what you've been doing so far, but the best thing is to get a small cotton ball or square of gauze, moisten it lightly, warm it up in your hands and dab gently at the genitals.  Do not wipe or rub.  This mimics mama's licking and encourages both urination and appetite.  Watch for spots of pee or poop in the enclosure - older pups may be able to eliminate on their own.

This website is extremely useful with orphaned mice and rats, and in the event you can't find anyone to help you by taking over its care, this will help get you on the right track with the little guy:

Best of luck to you both, and please let me know if I can help in any other way,

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!
