This is the hardest thing I have ever had to do, my 6 year old tabby SoSo was put to sleep today ...due to kidney failure ... She was wasting away .. Would not eat... Actions changed within the last week ... I feel so guilty letting her go... But she was starving herself as she was so weak and felt so bad... It's so hard to walk away and leave my love one .. She was my first pet and I miss her much... My heart is so heavy ... Tears ....
