Keep the cat / kitten on the bland diet for 1 – 2 days after the diarrhea clears up before starting to go back to the usual diet. Re-introducing regular food should be gradual, starting with 1/8 regular food mixed in the bland diet. On subsequent days the ratio should be 1?4, 1?2, then 3/4th regular food, before totally back to regular food.

Acute Gastrointestinal Disease
In most cases if your pet presents for an acute onset of gastrointestinal signs, whether it is vomiting or diarrhea, your veterinarian will recommend withholding food (and often water) for 12 to 24 hours, and in some cases 48 hours. This practice is often referred to as "resting the bowel". This approach is taken to reduce the quantity of unabsorbed nutrients in the bowel that may result in continued vomiting or diarrhea. Once the clinical signs of disease have subsided, water is usually the first thing offered to your pet. Providing your animal does not have an adverse response to water consumption, food is offered. You will hear many people refer to the food served for this first meal as a "bland diet". There is no universally accepted definition of a bland diet, but it generally means a diet that is low in fat and is easily digested. For dogs, this usually means cottage cheese and rice. Some cats will also accept cottage cheese and rice, however many cats will not. In this case they can be fed some chicken (or other low fat protein source such as tuna), along with a carbohydrate such as baby rice cereal. If your pet is willing and able to eat what it is initially offered, then they are generally placed on a veterinary therapeutic diet designed for the treatment of gastrointestinal problems. These diets contain moderate to restricted fat concentrations and are highly digestible. Depending upon the severity of your animal's condition, some practitioners will simply feed one of these commercially prepared products as the first diet offered following the onset of gastrointestinal disease.
After 12 hours, slowly reintroduce fluids and mild, bland food
Sometimes a 12 to 24 hour fast is enough to calm things down. If nothing at all goes in (except ), there's nothing to process and the diarrhea should go away. When you resume feeding, begin with the bland rice mixture, then slowly mix in regular food, reducing the amount of the rice mixture until the cat is back on a normal diet.
