Seriously pissed.

Not entirely sure what to tag this as, but maybe medical since it's involves my allergies?

Okay, so as a birthday 'present' I asked for a ferret, I did a lot of research both online and in physical. I have a few family members who have only owned ferrets, I follow people who own large amounts of ferrets. Basically I'm stocking up information on them. So for like three years I've only asked for a ferret, I even offered to save up my money to buy one

So, for my birthday present, my parents got me a cat. A cat. I'm allergic to cats, like cat scratch fever and this cat absolutely hates me. She claws at me, bites at me, hisses at me.. I've had a total of two allergic reactions from it. And my parents claim this is better than me owning a ferret..

P.S, I do take care of the cat. I feed her daily, give her water and clean her litter box, even pay for vet bills and other things. I've tried many sources on bonding, to try and get her less mean/defensive, but I can't.. I don't know what to do with her but I can't get rid of her, my parents already threatened that if I tried that, that they'd ground me and take my phone and friend privileges.
