Mine will attempt to ignore it but their bottle always goes and they run under my bed. :lol: They will sit and give it evil glares until I have to hoover under the bed, where Fiver will try to attack it, give up, and run off. :roll: I have have to pull the hoover away quickly before, so he doesn't get sucked into it! :lol: They aren't scared of it, but they hate the fact that I have to move them to hoover and get upset that all their toys/hidey holes and litter tray have been moved lol.
