Mice/babymouse exploded???


I was caring for a baby mouse, he was about 10 days old when he got bloat. That night, at 2 am, i got up to feed him, and his intestines werehanging out of his body. He lived two hours after that. There was little blood. He is gone now, but how did little kenny die? Did his bloat get so bad he exploded? I am confused. (His name is sadly ironic, i know)

Hi Machelle,

There are three possibilities that I can think of, but there is no way to know what happened without something called a necropsy performed by a vet very quickly after passing away.  I am not a veterinarian, so I can only guess, but here are the three options that pop into my head:

1.  Bloat.  I have NEVER heard of bloat causing the belly skin to rupture.  However, a baby mouse is a very fragile thing, and it might possible that a buildup of waste and/or gas could have resulted in a twisted or ruptured intestinal tract.  That does not explain the burst skin, however, and I really don't think that was the cause.

2.  Trauma to the belly.  The skin on a mouse's belly is very thin, even more so on babies.  What I think is more likely is that something injured him, such as a scratch or tear on something in the environment, which allowed his intestines to protrude.  I am not sure how possible this is, since I cannot see him or his environment.

3.  Deformity.  Mice which are orphaned, if he was indeed orphaned, are sometimes abandoned due to something being internally wrong with them that the momma can sense, but we cannot.  If that was the case, then any deformity in his abdomen, organs, or skin could have resulted in this situation.  There would obviously be no way to have prevented this possibility.

I'm sorry that I can't give you a better idea of what happened, but I have to be honest, this is not something that I have heard of occurring before, and I'm very, very sorry you had to see it.  I know how hard it is to keep baby mice alive, and when we lose them based on something we couldn't control it is so disheartening.  I'm glad he had you while he was with us.

Best wishes,

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!
