Exactly.
There is not a body of water anywhere that doesn't contain rat pee. When you then consider that weils disease can also be spread by amphibeans such as frogs and toads as well as animals such as pigs, cattle and even dogs it's amazing that anyone is still alive.
It really is a horrible disease but I'm not sure why it's being discussed just because @Eggs spotted a rat in his garden. lol
We tend to demonise any animals that aren't cuddly looking.
I'm just as happy to see a rat in the garden as any other visiting critter. ?
…you are welcome to come and get our rat visitor, Kev.
