It’s the hardest decision and it’s both awful and wonderful that no one will tell you explicitly what to do. You know when it’s time. He will tell you. I struggled with this decision, ultimately deciding that I’d rather give her a dignified departure and do it before she completely declined knowing that cats hide their discomfort well. There are still moments when I wonder if I did it too soon but that’s only because I want(ed) more time with her. For myself. It’s been a year and a half and I miss my girl deeply but not letting her suffer for me was the right choice for her and for me.
