Mine also hate the vacuum cleaner. I put them back in my room while I vacuum the other rooms but sometimes Cirrus won't cooperate. He's still scared but tries to hide from it and if I get too close to him he'll run. I don't drink coffee so there's no grinding noise here but I do use the toaster. Sunny likes to watch it but still will sometimes jump when the toast pops up. They also jump when my kitchen clock timer goes off. They hate the BZZZZZZZZZ noise it makes. They also jump if I use the garbage disposal. I guess I have some scaredy cats.
