<human>: Can you give me a shortened version of the text?

My situation: 19, female, just finished my first year of university away from home. After having the out-of-town experience, decided it was too expensive to do again so I moved back into my parent's house and will be going to university here. I have a 8 hour job from Monday to Friday. 

I currently do have a pet dog but she is more of a family dog then my own. So I want to buy a bunny. The one I am looking at is 12 weeks old Netherland Dwarf Bunnies, a [harlequin] Sex of bunny is unknown for now. He/she is fully weaned and and well handled. The breeder has offered the bunny, cage, feed, and shavings for $100.

This will be my first pet other then my dog. With my steady summer job, I will be able to support it financially. But my mother is really against pets in general. The only reason I got my dog was because my step-dad and step-sister wanted a dog too. But it is just me asking for a pet.

I just don't know what to do to convince her. If I cannot convince her now, I will not be having an animal companion besides my dear old dog till I move out in 3-4 years.
<bot>: Mom won't allow pet bunny even though I have clearly shown my independence, competence, and have the financial stability to support the animal.
