they have a itchy spot
No, there is no reason to kill a guinea pig for scratching someone.
This is most likey a way of the Guniea Pig telling you he enjoys what you are doing. My Guniea Pig does the same thing when I scratch his belly.
that's a question only guinea pigs can answer if your guinea pig doesn't bite or scratch when you pet them then yes if they do then no
Overall guinea pig supplies cost about £60-£80 ($100 - $130) if you are starting from scratch, but a top up on supplies will cost about £5-£7 ($10 or so).
it will scratch itself with its foot all the time and will squeal loudly and throb its body
Some just don't like it, but it depends on what you mean by "Scratch"
It is spelled "guinea pig". You got it right! :)
