That’s a heavy hit. But that’s also amazing that you all got to spend 18 years together. Thats really cool you got to spend so much time with one another. (^_^)
I am so sorry to hear of your loss. I lost my cat who was 17 almost 18 from his kidney's failing. I couldn't get him to a hospital because it was around when my husband was leaving for work. I sat with him and kept him as comfortable as I could. Again, so sorry for your loss.
