A cat that always meows in a long tone may be uncomfortable, hungry, etc. The owner can feed the cat some snacks that the cat likes to eat. If it still keeps meowing, it may be in estrus. Generally, the meowing will last for 5-7 days. During this period, prepare some toys for the cat to help divert the cat's attention. If you don't want the cat to mate, you can choose to sterilize the cat. You must go to a regular pet hospital for surgery to avoid the cat's life danger.
