Why do Cats Meow?

2. A meow for every occasion

Cats are smart, and they have different meows for different occasions. If your cat is greeting you as you come in the door, it might give out a series of multiple meows showing he's excited to see you. A quick meow might be a quick hello. A meow that is mid-pitch may be him asking for food. A long-drawn-out meow may be more of a demand. A low pitch may indicate a complaint, whereas a high pitch might mean he is angry or in pain, which you would likely recognize instinctively.
