I've had one cat ,Tabby, who I lost after a few years. I came back from a week-long holiday, the next morning my brother found her on the side of the road. Even now, a good few years on, it's painful to remember losing her.
I'd post some pictures of my current cat, Shadow, but the downstairs computer (which holds all the photos) isn't on and I can't be stuffed going downstairs for that. Suffice to say that she's a lovely little catter.
