I'm not letting you go no matter what.

It has been a couple of weeks since I returned home from university. It was not a very happy visit. My cat has not gotten better from her thyroid problem. This is a sad moment for me, because ever since my family has gotten a new cat, my older cat has been upset. Feeling unwanted, she often is isolated. She only slowly approaches me because I felt that my loyalty was with her. I understood her feeling of abandonment, and paid more attention to her than my younger cat.
In the past 1/2 year or so, she would sleep on top of me while I was sleeping, or crawl up into a ball at my lap when I was sitting. I don't know exactly when, but I have grown to love my older cat, and would do almost anything for her. I returned home this weekend to discover that the topic of euthanasia has turned up. This pains me a lot. I understand that my family's financial situation is dismal, but a part of having a pet is to devote yourself to them. Your pet is your friend and family. Euthanasia shouldn't even be an option unless there's no way to treat the sickness. You don't put your family member and friend down just because it is inconvenient to pay for their health. That's horrendous, even by my standards.
There's no way anyone can take my precious baby away from me. Even if I have to quit school to be able to pay for her treatment. Hopefully it won't come to that.
