My cat is convinced that the sound of the water sloshing in the dishwasher means that there is a flood occurring somewhere near the kitchen. If she wants to eat while it's going, she stands on the nearby stairway, stares me in the face and says "Rra!" every few minutes.
It took me a while to figure out what the problem was and to put her food bowl up high where the flood couldn't get her.
After I figured that out, it was easier to figure out that "Rra!" while the microwave is running means 'It is dangerous for the cat to eat in the kitchen while the cyclotron is in operation.'
