Help me get a pet cat!

Hello! As you can tell, I've never adopted a pet and I want to adopt a pet cat but my mother doesn't allow it :( She says that I'm not even financially stable enough to feed myself let alone feed the pet cat. Therefore I want to prove her wrong, please help me get a head start in getting a pet cat by donating! Of course I will be saving up so that when the money is used up I'll still have money to raise my pet cat!
