I find that hard to believe Bobbi, I really do. Not only have I seen both (in France I, very regularly, used to drive carefully in the evening through flights of bats and they took up home in my unused bread oven - the babies look like bunches of furry grey grapes) but rats are a heck of a nuisance here and have cost us a lot of money in poison. One came out to die on the lawn the other month - the dog goes nuts trying to dig them out and kill them. He is a good ratter if he can reach them. Do you live in a flat?
I don't disbelieve you, you are always honest and open, but I really am 'gobsmacked' is, I think, the word. :)
