Abby does. Though, now after almost 9 years when I take it out I actually see her run off instead of a blur, LOL She kind of watches to see what I'm doing, and sometimes if I'm vacuuming on the otherside of the room, she is ok with it if she is on the otherside. But if I take it out and place it on the same side of the room as she is, she's gone!
Chynna on the other hand loves the vacuum. She actually chases me around when I have the vacuum out trying to get me to vacuum her with the upholstery brush. If I'm in the dining room she's on the table meowing at me and brushing up against me when I'm vacuuming the dining room chairs, or on the coffee table when I'm vacuuming the area rug in the living room. She wasn't always like that though. Years ago she always ran and hid too, then as she got older she stayed in the room and one day she let me vacuum her. Now she's addicted!
I think part of the reason Chynna likes the vacuum is because she's 15 years old and her hearing is less than what it used to be. However, she's loved this vacuum ever since I got it back in 2000. She didn't like my Sears Kenmore at all, lol
Charlie hates it! Now that he's an indoor kitty he can't run too far from it. But thyats because he had a previous owner at the age of 4 months old when we got him from the RSPCA. Loud noises are a no-no. We're building an enclosure over the next two weeks though, so he can get away from noisy plastic bags and things
Mine vary between terror that makes them freeze and annoyance
Boomer freezes and will try to get under something nearby
Magnum hisses and runs, Bumper just runs
Scully keeps a close eye on it to make sure it doesn't get too close but if he is on a sofa etc will not move, if he is on the floor, he will wait until it comes close, smack it and run
Maggie turns herself practically inside-out trying to run away from the vacuum. Lola will casually walk out of the room as I vacuum nearer to where she's sitting. Cleo will lay on the sofa and watch me vacuum, it doesn't bother her at all.
Much will just casually move somewhere else. Carly watches it suspiciously and will walk to another room. Poor Lucy (who also hates thunder) will go to the other human parent and sit very nervously beside that person (DH does most of the vacuuming so it is me she is near). She will sometimes just lean into me. Doesn't want to be held, just sit nearby.
Nikita freaks out over quite alot of loud electrical or mechanical noises. The vacuum is an evil cat killing machine from her point of view. So is my door buzzer (she loves visitors though and wants to sniff and lick the face of everyone that comes inside), my alarm clock, cell phone and landline phone are also thing that will make her startled and run away.
The vacuum is the only one that makes her run away and hide though.
This is one thing my three boys are united it...their hatred of the evil, vile, cat-eating vacuum cleaning monster. All of the will run from it. I have to be very careful to make sure it doesn't sneak up on Forest...if it takes him by surprise, he'll jump up and go racing away, but with his coordination problem he slams himself into walls and furniture and doors in the process. (Once I didn't realize he was sleeping under the bed and I turned it on right near him...I almost scared the poor guy to death!)
Surprisingly, Bagheera, the oh-so-skittish one... is unaffected by the sweeper. Mighty Kahn runs and trembles. Noel looks at it with disdain and then meanders away when it gets really close.. depending on where she's sitting sometimes she won't even move. And the Marbled Menace hides and we don't see her for quite some time. We haven't run the vacuum for Pogue yet... he just arrived and bless his little trembling heart.. I don't want to give him a heart attack. He didn't seem to mind the blender too much, though.
