Some cats will meow before they die. This meow has no specific meaning. There are two reasons for the meow. One is that the cat is feeling uncomfortable when it dies, and the other is that the cat wants to say hello to you. Many cats are listless and have no energy when they are about to die. They will struggle a little and make a cry before death. Some cats are relatively calm when they are about to die and die as if they are asleep. These are normal.
