Help for a little angel

Hello! My name is Natasha, I'm a Russian young girl that moved to Romania because of some problems in my familly. I have been struggling with my studies, money and other things. The only thing that was still keeping me going was my cat. I felt like it knew what I was thinking, always there for me, but last month I've found out that it may have Chronic Kidney Disease. I don't have the money to do anything, and I don't know what I would do if something happens to my little Angel. I need your help to save it and make my life bright again. Thank you.
