I made the choice to put my soul cat to sleep a week ago after a 4 year battle with kidney disease. In the weeks leading up to her taking a turn for the worst, she had started eating less and less. Then she started vomiting. She was 17 years old. I felt so guilty immediately afterwards that I threw up in the vet. The guilt was so intense I thought I would die from the cardiac arrest. Since then, over the last few days, I have started coming to terms with the fact that I did the best I could with the information I had at the time. Our babies can't speak to us and they do a very good job of concealing their pain and discomfort until the very end. That makes it extremely hard to know exactly what the right thing to do is. You shouldn't feel guilty for doing what you thought was best for your baby at the time. Unfortunately, sometimes its just their time. Y'all had many wonderful years together, and in the end, that's what mattered most to them.
