With short, uncomplicated diarrhea a hungry diet for one or two days will be fine. During the first few hours you should reduce the amount of water (especially if there is vomiting). An important point is to ensure the rest of the cat.

To compensate for the slight loss of fluid in the body (if there is no need for intravenous drip injections), oral (through the mouth) administration of liquid in small portions is used.

You should start to feed the cat on the second or even on the third day. Increase the amount of feed gradually. The use of rice, oatmeal decoctions shows good results in treatment of uncomplicated diarrhea. Antibacterial therapy is not indicated. After treatment, you must follow a diet, otherwise there is a chance of relapse and transition of acute diarrhea to chronic. If diarrhea is a consequence of other diseases (infection, invasion, poisoning, etc.), in addition to all of the above measures, it is necessary to treat the underlying disease. In this case you need the help of a qualified specialist. Depending on the severity of the process the vet can prescribe:
