Help

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

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

How can I convince them?
