How Can I Convince My Strict Mom To Let Me Have A Hamster?

First of all im working at getting a hamster too :]
when i first asked my mom she told me no way! I  then asked her what happens if i work for it....u know the regular stuff, cleaning.......helping out, whatever she said yes. She told me that  i would have to work for a while though. I think she said i would have to work for about 3 months. So maybe u should try asking your mom if there is anything more u can do to help around the house. When she thinks your responsible enough i bet she will be willing to buy u hamster. Just make sure u don't bother her too much about if follow her rules and let her do the leading......trust me it pays off. (i also gave my mom the "i think that doing this will make me more responsible" speech)

Tell her you will look after it. And you will do a chore everyday be it washing up in the evening or hoovering. Then she will understand you are responsible
