Thank you for the additional information.
If you are seeing feces being passed (even abnormally shaped feces), then constipation is unlikely here for this wee one. This is because for any formed feces to pass through her there must be room in the gut for it to move through. If her GI was obstructed (by foreign material or feces from constipation), then the only type of feces we could see would be pure liquid diarrhea since that would be all that could squeeze by whatever was blocking the gut.
Therefore, I'd be more concerned that the feces situation is due to her trying to hold her feces (thus leading to them being harder or strangely shaped) because something is causing her pain (and the muscular action of passing feces is likely even more painful for her). This being hunched up and unwilling to move once you put her down is very suggestive of severe pain. Since mice are very small in stature, it can be difficult to localize where she is experiencing discomfort but hunching is often a response to pain of the back or the abdominal contents.
Therefore, I would be more concerned that this could be a mouse who have experienced a recent pain inducing trauma and now is too sore to eat/drink/pass feces comfortably. Or, an even more worrying issue, is that she may not be able to urinate. This is more often a problem for male animals but if she has experienced a urinary blockage due to a bladder stone then she won't be able to urinate, will be very sore, and will deteriorate quickly as the unpassed urinary toxins leech into her blood and cause toxemia (which can be fatal). And of course, we do have to consider any disease (ie infection, tumor, inflammation) of internal organs could also manifest as pain and collapse in the mouse.
So, while there are other constipation relieving options (ie canned pumpkin, feline hairball treatments, metamucil, etc), I am quite concerned that this is not a constipated mouse. Furthermore, I am quite concerned you have a severely painful mouse with a late stage condition that is progressing to a stage where she is severely affected (since prey species instinctually hide illness and she is obviously too ill to do even that) and could carry a guarded prognosis without intervention.
Therefore, in this situation, it would really be prudent to have her examined by a vet in person. They can determine by palpation (or by popping the ultrasound probe on her belly) if she does have a blocked bladder or if there are any abdominal masses or issues triggering her pain. They can also provide mouse safe pain relief (ie metacam) to allay her discomfort. Depending on their findings, they can give you an idea if this will be something you can treat or if this is something that requires you to end her suffering.
Just in case cost is a concern, you can take advantage of the free first consult offer that both VCA veterinary hospitals (LINK
) and Banfield Veterinary hospitals (LINK
) offer. This would be a means to have a vet check her in person and aid you in relieving her current suffering.
I hope this information is helpful.
