I am an animal lover. Me and my 4 siblings have 5 guinea pigs, 8 chickens and 1 dog [who is really my parents]. 4 of the chickens and one of guinea pigs are mine. I would really like some pet mice. Would love them, really. I have wanted them for about a year now, so I am quite sure I want them. Dad, however, I think, doesn't really want pet mice. I am not a big fan of wild mice, I mean, they are cute, but a bit of a nuisance. I only want pet colours like patchy etc...Not natural brown. I have saved up and am very responsible. How do I convince my Dad to let me get pet mice?
