In the past 2 days I've had 2 mice with what I believe to be a prolapsed rectum. Basically a pink thing sticking out of their bottom. The first one I soaked in a sugar water solution (had read on here that was a good idea for a prolapsed snake, so I thought it was worth a try), but after some more internet searching, I found that apparently the outlook for a mouse with a prolapsed rectum is not good. Even if it goes back in, it is very likely to prolapse again. The sugar solution did not seem to be having an effect anyway, so I decided to feed it off.

Now, about 24 hours later, I just found a 2nd mouse with the same problem. What's going on? I'm really worried because both of these mice were in my female grow out cage, and those girls represent my first 4 successful litters. I was really looking forward to them getting big enough to breed, because of all the rumors that things go much smoother with the 2nd generation.

Any ideas what to do or what is causing it?
