What a lovely blanket! I lost my cat, Lily, in late January. We also had many lengthy conversations. Usually she was asking me for treats but at the end I knew she was asking me to help her feel better. I know what you are going through and I agree with Jan that there is no set timeline for grief. People talk about the stages of grief but I can say from my experience, they are not linear. It's not like you go through one stage and then the next - you can go back and forth. You just have to let yourself grieve as much as you need to. I'm glad you and Nile are there for each other. He undoubtedly misses Sphinx too (great names for cats, btw).
Thank you and sorry for the loss of your Lily. It was the same with Sphinx, I could hear it in the tone of her voice that she was asking for help. It pains me that the only option I had was to let her go. I'm sure that wasn't the sort of help she wanted, but it was the only I could offer her. I'm so grateful I have Nile. I'm forever thankful for my spur of the moment decision 12 years ago to take him home with me.
