Thanks guys! It was the weirdest thing last night as I kept thinking I could hear her breathing. And going to the toilet on my own as she always had to be there when I went. But heaven help you if you happened across her in the litter tray. Looks could kill!
I have another cat but she isn't touchy feely at all, she's completely driven by her stomach. I feel guilty for thinking I wouldn't be as upset if it was the other way round. I miss being able to pet and give Millie a hug, and having her follow me around. But looking at that photo which was taken last May I can see how much she had changed over the last months of her illness. I think she was just tired of fighting and it was her time to go. The last act of love is the owner taking on the pain of bereavement rather than the animal living in pain.
