I had never been interested in guinea pigs till a few months ago when i was at my friends house and she had two really nice guinea pigs so I asked my parents if I could get a guinea pig and they have said yes! which I am very happy about xx>>> and my friend is helping me learn how to look after them and I know it is best to get them from a rescue centre and not a pet shop like pets at home because they are treated like products not animals but my parents won't let me! what should I do to persuade them they are much better off from a rescue centre!??/
