It is normal for cats to have their stomachs rise and fall when they breathe. Cats breathe through the chest and abdomen, so their stomachs rise and fall when they breathe. If the cat’s belly rises and falls quickly or slowly, there may be a disease in the body, causing difficulty in breathing or accelerated breathing. It is recommended that the owner pays attention to it. If the cat is in poor condition and is accompanied by symptoms of vomiting and diarrhea, the owner should send the cat to a pet hospital. Carry out examination and treatment.
