First check whether the cat is in poor spirits, lacks energy, does not like to exercise, or has diarrhea. If the female cat is normal and has no major problems, it may be morning sickness caused by pregnancy or indigestion. In this case, the owner does not need to worry, and can be adjusted by feeding gastrointestinal drugs. If the cat has the above condition, it should be a disease in the body. It is recommended that the breeder take the female cat to the doctor in time to avoid serious deterioration.
