Short breathing and rapid abdominal rise and fall in cats may be caused by respiratory diseases, lung diseases, ascites, epilepsy, allergies, feline nasal congestion, feline bronchial asthma, heart disease, etc. If your cat frequently suffers from this condition, it is best to take him with you. The cat should go to the pet hospital for examination to avoid delaying the condition. If the cat has this condition after being frightened or the weather is too hot, it can usually be relieved on its own.
