Help

So my instructor has a littler of Persian ragdoll Kätzchen and the are gorgeous. I have wanted a cat for a long time now and this is the perfect opportunity. Normally those Kätzchen sell for $1000 but my instructor is selling them for $500 and students get $100 off.

My parents have always sagte no and they don't even have a reason. No one in the house is allergic to them, our Hunde are just as much of an annoyance to the wildlife, our Hunde don't care about Katzen and our Hunde shed heaps of pelz anyway. Plus we live on a farm and we have mice in our stable.

How can I convince them?
