Having to put my beautiful cat down. WARNING. VERY EMOTIONAL

The hardest thing I've ever done. I loved her soooo much. She's been my baby girl for 13 years. She developed a blood her back which affected her hind legs. Zero mobility and they were cold to the touch. I tried to help her. I built hammock wheel chair. But she didn't take to it. After a month of me trying to find ways to fix her. There was no other option. I could see in her face that she knew what I had to do. We were both exhausted. Idc about me. just felt like a horrible father to her. I couldn't handle it. I felt like she was being tortured. My heart hurt. And it will always hurt when I watch this. Im not a cat killer. I was helping her.
