if it is played softly, will not disturb your cat. But if you
play your music at full blast, the cat will not like it at all ~ just
as little as it likes any scream or loud noise. Cats have a much
better sense of hearing than we humans. Your cat can hear tones
that you can no longer hear. When a rolled up ball of paper
drops rustling to the floor, the cat knows exactly where to
look for it. It has such finely developed ears that it can distinguish
the patter of mouse paws from other sounds in its vicinity.
Now, perhaps, you have some sense of how much your cat suffers from loud noises. You may be able to understand why it will leave the room suddenly, and you will not be able to find it for the next few hours.
