Most cats are scared of the unknown. They hate noises and run and hide, don't they? I'm not showing off or anything, but when I hear some strange noise I haven't heard before I might get a bit jumpy but I don't want to run away. I'm a curious kitty (I know, us cats are famous for curiosity and my mummy isn't happy that I am this curious about everything). I can't help it, I like to investigate.
When I first heard the vacuum cleaner I was very scared, I admit.I was only a baby and it was a horrible loud noise that hurt my ears. But Mummy was always with me, or my granny was, so I realized it was nothing to be scared of. If they weren't scared, then why should I be? I am a clever little girl, after all (so they keep telling me)
Anyway, this little video here is of me when I was little and hearing my granny doing the vacuum cleaning. I am in the living room with my mummy.
