Cats in the wild have a wide range of vocal expressions; they hiss, growl, spit, and scream. The regular “meow” a cat gives a human is different, and some cat experts believe the sound developed partly to communicate with people. We associate it with the cry of an infant, and meowing gives results.
Cats are good at varying their meows, and the cat owner learns to distinguish a meow saying “I want to go outside” from a content cuddle meow. Cats can vary the frequency, pitch, volume, tone, and length of their meows, and no two cats sound exactly the same.
If your cat starts meowing obsessively or exhibits other sudden changes in behavior, you need to take him or her to a vet, just to be on the safe side. Other than that, enjoy learning the language of your cat. It’s possible to learn to communicate well with them, and knowing what your furry friend wants opens a new dimension to your relation.
