I confess that I'm a sucker for a cat.

As an over-the-road truck driver, I find a cat to be cleaner, quieter and very much more low-maintenance than a dog.

As studies have shown, pets seem to lower blood pressure and incidences of depression.

I wonder, though, how hard-wired are we to being pet-owners? Even though they now serve no useful function than to provide (degrees of) love and affection...



Well, we have so many co-evolved bacteria that work to keep our bodies functional and healthy that it's basically pointless to define this cell as "me" and that cell as "not me." So why would it be silly to wonder whether we have such close attachments to animals?

But a better question might be, how did cats manage to biologically acquire our species to serve as their support staff?
