My cat doesn’t mind the vaccuum. Most loud noises for that matter (motorcycles, trucks, bubble wrap and plastic bags). She’ll let me brush her and clip her nails. However, she has absolutely no tolerance for Fleet Week: particularly the loud Blue Angels flying over or near our house. Or even rather far away.
She low walks to the middle of the house, or under the bed. By low walks, I mean she slinks with her belly to the ground away from all windows. And she will act like this for hours. Initially, before we knew what was going on, we thought she was ill and she almost had a vet trip. (Luckily we figured out why she was acting so weird when a plane went over the house — she was acting like that to the distant sound…)
Anyway, my cat, she hates Fleet Week.
