Cats with watery stools need to go to the hospital for examination. Generally, it may be caused by feline distemper, enteritis, parasites, or improper diet. Therefore, the cause needs to be confirmed and then treated accordingly. You should pay attention to your cat's diet at ordinary times. Do not feed milk, squid and other foods, which can easily cause indigestion in cats. Occasionally feed probiotics to help regulate the gastrointestinal tract, and deworm the cat's body regularly.
