What are the reasons for a cat's repeated vomiting and diarrhea?

It is abnormal for a cat to vomit and have diarrhea. Sudden changes in cat food, gastrointestinal diseases, and viral enteritis may be causes. If a kitten vomits and has diarrhea frequently before being vaccinated, it may have feline distemper. It is recommended that owners observe and record vomit and stool, and seek advice from a pet doctor promptly if the cat has repeated vomiting and diarrhea within a day, as this can easily lead to severe dehydration and pose a threat to the cat's life. If the cat is an adult and has complete vaccination, it may have common indigestion or bacterial enteritis.

Sudden change in cat food

Suddenly changing a cat's food brand may cause gastrointestinal discomfort, as the cat may be unable to tolerate new food ingredients, leading to adverse reactions and vomiting or diarrhea. When changing a cat's food brand or offering new snack cans, owners should make a gradual transition while maintaining the cat's previous eating habits and slowly changing the food. You can refer to the "seven-day food change method." Cats who vomit or have diarrhea due to this reason need to be fasting for one day, after which probiotics can be used to regulate the cat's intestines. Follow the principle of eating small meals frequently and feed easily digestible food.

Gastrointestinal diseases

When a cat has gastrointestinal diseases, it may vomit and have diarrhea. The cat's mental state is usually poor, and it may stop eating and drinking. If the gastrointestinal inflammation is severe, the cat may even bleed in the stool and produce watery stools. If dehydration and collapse occur, it may threaten the cat's life. Since gastroenteritis can have severe consequences, it is recommended that owners seek medical attention immediately, allowing professional doctors to diagnose and treat the condition. Treatments may include fluid replacement, adjusting water and salt balance, using antibiotics to eliminate inflammation, and regulating the cat's diet.

Feline distemper (also known as feline panleukopenia)

Feline distemper is a highly contagious disease that causes significant leukopenia. The disease progresses quickly and has a high mortality rate. Early symptoms include increased body temperature, repeated vomiting, and diarrhea, and some cats may even bleed in the stool. Cats with this disease are at a high risk, and delaying treatment can lead to death. If a cat suddenly vomits and has diarrhea, and its body temperature rises, the owner should suspect a viral infection and seek medical attention promptly. The course of feline distemper is about seven days. If the cat can survive the weeklong treatment, its white blood cell count will rise, and it will have an appetite, indicating that the cat is on the road to recovery.
