Mice at Schiphol are probably cleaner than many people living in urban slums, unfortunately.
I doubt cats are a cure if it was rats. One of the times I was in Singapore, you could see the rats wondering along the side streets at boat key. These were big rats. There was an average cats sitting on a chair at the end of the restaurant watching them, I swear the rats were bigger. Though Singapore cats are all skin and bone.
