Cats have a normal appetite, but symptoms of diarrhea may be caused by feline distemper, bacteria, parasitic infections, etc. When owners find abnormalities in their cats, they should immediately take their cats to the pet hospital for examination and treatment. Pay attention to adjusting the cat's diet, do not feed the cat food that is too salty and oily, change the cat's water source frequently, feed the cat some probiotics to help the cat's gastrointestinal digestion, and deworm the cat regularly.
