A cat's incessant meowing is usually caused by the following reasons: hunger, illness, stress, being in heat, being startled, etc. If it's just meowing and there are no other physical discomforts, then it's normal and the owner generally doesn't need to worry too much.
If the cat is meowing incessantly and abnormally, it indicates an underlying medical condition that could affect its normal development. It is recommended that the owner take the cat to a reputable veterinary clinic promptly to prevent potential health problems.
