2. High pitched sounds
While cats hear low-pitched noises about just as well as we do, they can pick up high-pitched sounds much better than humans. High-pitched noises – cats come in ways you would not expect. Ambulance sirens, loud music, hairdryers, vacuum cleaners, or even your phone’s ringtone are some of the high-pitched sounds that cats hate. This is another reason that we should never shout at our kitties as this only causes stress and anxiety.
