Rats
"Each night I find myself in the middle of a ballet of 20 to 30 rats. I have set traps and I have devised constructions over buckets of water. All has worked well... but the rats have escaped. Rat-poison has no effect. As a last resource we have caged a cat. It is not much fun. I do not like it at all that the rats run over my body when I am asleep ".
