Pregnant mouse?

[Macropodus]

Abandoned. Really? Hmmm, that's strange... I thought our invaluable advice was that if simply being alone or with unfamiliar mice got them to neglect their young they woulndt be as effective as a species. Supposed to be just wrong type of feed. 99/100 times it's wrong type of feed, so I guess this time is the 1/100 of a time that's it something else?

This, therefore, has become quite a perplexing issue. Could this be the 1 out of a hundred times that she didn't fulfill her motherly duties because she was isolated or mixed with the other, unfamiliar mice, instead of pulling the largest female mouse from the new recently acquired feeders and put her together with the pregnant mouse in a very dark, warm, quiet place with little to no disturbance?
