If a cat eats a plastic foreign body, pay attention to see if the cat can pass it out. If it does not pass out for a long time, take the cat to the pet hospital for examination and treatment. Cats eating foreign objects may be caused by a lack of trace elements in the body. The cat must be supplemented with nutrients in time. If the cat eats plastic, it must be stopped immediately to avoid diarrhea and vomiting after the cat accidentally eats it. In severe cases, it may even cause the cat to suffocate and die.
