A. Your cat sounds like she has a painful GI problem that will most likely not be responsive to at home care. I recommend getting her seen by a vet for a proper examination and potential tests to figure out what is causing her diarrhea so that she is treated quickly and appropriately. Hiding cats in distress almost always need to be seen by a vet to help them with their illness/issue for their overall care and well being because cats typically don't show pain unless things are really bad off.
