Why don't you just give Snow away.

Your aunt's daughter suddenly is allergic to their 8 year old cat??? Yeah right. I hope that poor cats gets a good home.

That's why I wrote it might not be true. I was told that though.

I agree with Madusa
Your better off finding a new friend with more feelings toward life.
Or...you can sit down with her and have a long kind chat with her about how important it is to care for an older cat just like it is your grandparents.
The older/sicker cats need us the most.Of course kittens are super fragile and need extra care but she needs a good learning conversation.
Teach her how important cats need daily water so they don't get dehydrated and die and so on.

Take her on a visit to your Humane or SPCA, and have someone there explain how many cats need homes, and WHY.

IE some of the excuses people use....

Well I hear that cats can sense if someone does not like them. I trust that.

You do have every right to be mad at your friend.
