Solutions for cat diarrhea and dehydration:

1. Fasting. Stop feeding canned cat food, hard cat food, meat and other foods that are difficult to digest, and fast for one day.

2. Keep warm. During autumn and winter, the occurrence of diarrhea increases. In the cold season, more attention should be paid to cats' drinking water, keeping warm and other issues.

3. Replenish water. Replenish plenty of water, preferably cold boiled water, not tap water, because tap water is not hygienic and clean and will cause secondary irritation to the cat’s gastrointestinal tract.

4. Supplement glucose. In addition to replenishing water, you also need to replenish glucose to prevent excessive weakness.

5. Seek medical treatment promptly. If you are in low spirits, have a fever, are vomiting, or have green or yellow water in your stool, you may be infected with a virus. You should go to the hospital for testing first to see if it is feline plague, which requires antiviral treatment from a doctor.
