Dear Taylor,

to add another note:

rats are beeing considered as very intelligent animals, and at least this seems to be true for the rats of my home town, Stuttgart,
where it was discovered one year ago, that they have entered the University library and have spoiled -
by shitting on them -
about 8000 books of social and economic sciences from the sixties to the eigthties of the last century.
