A. You do not mention age, species or any other clinical signs so it is very difficult to speculate. Colitis or inflammation of the lower bowel will produce more frequent, loose stools with mucus and can be caused by some parasites, dietary changes, stress and infections. A highly digestible balanced diet enriched with fermentable fiber can be protective in many cases
A. You can try with holding food for 12 hours, then offering a bland diet, such as boiled white meat chicken and boiled white rice mixed 25%:75% in small, frequent feedings. If stool returns to normal in 12 hours, transition to normal diet. However remember that there are many causes of diarrhea, from parasites to liver disease, and if it doesn't completely resolve she needs to be seen by a vet for diagnostics and appropriate treatment.
