They are clearly so much more than that. I call my two boys my companions, my friends and my family. I care for them like I would for a member of my family, I worry about them when I'm gone and I've lost count of the times I leave the house only to double-back just to make sure I didn't leave a window open they might fall out of (I live in the city and they are strictly indoor kitties, plus 13 years old).
In short, I do and worry about things concerning them to a degree that the term 'pet' doesn't cover.
