Is a pet your best friend?

I definitely think that a cat can be considered a best friend! In fact, as the time goes on, I'm seeing that our cat is getting closer and closer to all of us. She can sense when we're not feeling well and will come sit by us or climb up beside us (very rare for her to do that other times!) and... well she just seems to be tuned into us and it's getting more and more pronounced the older she gets. We've joked that sometimes it's almost as if she can read our minds. Now if that isn't the kind of relationship that can be considered a best friend, I don't know what is! :-)
