It doesn't matter in what country one lives, there are mouse "rats" big everywhere especially in big city or in the countryside near the river and lake, (especially rats of river they're pretty big) . If you google it you can see that they exist and they are on the rise too because they adapt and they keep on resisting to the deratization. Well if you've never seen one before you're very lucky.
I now live in Holland but I know people who have seen them in England , France , Italy, Sweden, Thailand, Spain, Russia and America. They're everywhere and when I was searching for a means to get rid of them, I chatted with people who had the same problem as mine thinking I was the only one who had seen a rat so big but we exchanged pictures and you know what mine was little in comparison of some of them ( ̄∇ ̄")

Well if all the mouse were so fluffy and cute I wouldn't mind if they lived in my garden, but all the mouse that I've seen so far are bigger than my cat who runs away as soon as he sees them ( ̄∇ ̄")
