The reason I ask is sometimes when I'm listening to music while house cleaning or just watching an action movie, I notice Clover always leaves her comfortable and favorite place in the livingroom and goes into the bedroom under the bed where it's quiet. I can't help but wonder if and how much damage am I inflicting on her?
Is this a common reaction from cats in general?
Cats' ears are uniquely designed to draw sound into the ear canal, which enables them to hear sounds like a mouse rustling in the brush 30 feet away. By the same token, their ears are more sensitive to higher amplitude of sound. It is common knowledge that humans' hearing can be compromised by repeated exposure to loud music. In my opinion, cats are more susceptible to potential deafness from the same cause. Incidentally, an army experiment with cats backs up this theory.
Your cat's reaction to the loud music and/or excessive noise frequently found in action movies is an instinctive act of self-protection. I'd heed the signals she's sending, and tone down the volume when she is in the room.
