OK, lets dispel a few myths about rats:
The rat in the video is not a rat found in the wild in this country as the video explains and is not a giant rat, it is a normal sized pouch rat.
Rats will never go for your throat, this myth came about from a theory that rats assume they can jump over anything to escape, thus to escape they jump upwards, a rat can jump no higher than about 2ft, and they will only jump if cornered and only to escape, they will not attack you as long as they have a means of escape, when ever I have been attacked by rats, it was because I was digging out their nest, they then only bit the toes of boots, the terrier made sure they got no further. I have had rats run up my legs and up my arms but only ever to escape, not to attack me.
Rats are not so prolific that you are no more than a few yards from one, its a joke, this nonsense comes from rats living in sewers, if there were rats in the sewers and the sewers were totally over run with them this myth would hold a little water but these days pest control keep this problem to an absolute minimum in most areas.
Where there is one rat there is more, yes you are right, there is usually more, that applies to just about every species on the planet but just because you have seen one rat doesn't mean you have a rat problem, it may have been a rat just passing by. they do live in our countryside.
Rats excite people like no other creature! if you seen one the whole world will be over run and we will all be eaten by giant sized rats!!!!!!!
Rats are extremely easy to eradicate, I don't care what anybody says, when I went out on a rat job, I knew I would kill every rat with one visit, mice however are a bigger problem!
