A cat’s ears are tuned to hear high-pitched sounds. They’re placed fairly close together in the head and cats have evolved to hear high-pitched sounds much better than low-pitched sounds because most of their prey animals. Rodents, birds all communicate in a very high frequency. ….so cats hear high frequency sounds much better than low-frequency ..cats respond to their name much better if the name terminates in a high-pitched sound. For example Lancelot ends on a low sound, he’s much less likely to respond to that than if we call him Lancie.
