Probiotics for cats can increase the number of beneficial bacteria in a cat's gut, helping with intestinal motility and improving problems such as constipation and indigestion. On the other hand, cats may experience symptoms such as vomiting and diarrhea due to indigestion. In such cases, owners need to temporarily stop feeding their cats and give them an appropriate amount of pet-specific probiotics.

If the cat continues to experience severe vomiting and diarrhea, it may be due to a virus, gastroenteritis, pancreatitis, or other illnesses. In such cases, the owner should take the cat to a veterinary hospital for examination immediately. Sometimes, even after a cat has just recovered from an illness, it is recommended to give it probiotics.
