I am so sorry for your loss. While I don't equate the life of a pet to that of a human, I have had several "fur children" through the years, they become such a part of your life that losing them is very hard. I had a big husky mix girl that lived to age fourteen and a dainty tuxedo cat that died at seventeen, that's a lot of years shared, I felt the loss deeply, I held them both as they were euthanized.
My current cat is a dilute tortie named Lizzie. She makes me laugh out loud at least once a day, I don't know what I would do without her. This week I was missing a tube of cortisone cream, so I looked under the bed and found it, as well as two boxes of Kleenex that had also gone missing. I knew Lizzie did it because one of the boxes was shoved up in the box springs. Why Kleenex, and how she managed to get it up there I have no idea. She has been known to find things, but usually she brings her treasures to share/show off, obviously she was keeping these to herself, the little thief. I guess that also explains the missing box of cat nip.
