How can I pursuade them into buying me a hamster?

I've been trying forever to have my parents get me a hamster and it seem to never works! :( All I want to know is what is a good way to get my parents to enunciate yes!!
Blind horse! relief me?
Answers:    Try showing more responsibility around the house, they probably think they will end up taking care of it after adjectives (i know you say NEVER! now, but think almost it, will you really take time EVERY DAY to top up food water, and take your hamster out to play?) If yes, speak about your parents you understand this then show them by
a) not fighting w/ brother/sister so much
b) doing what they enunciate the first time they say it
c) picking up extra chores and telling them its to prove your responsible.

I hope this help, GL!
My mice won't run within its reins?
Tell them a hamster is very edible--tastes like chicken.
If a mouse breaks his foot.. Will it die?   Is near a paint thats out of danger for guinea pigs?   Bringing Pets to Korea?   Help! Horse trouble! Is he gonna die?
