I would say my grumpy cat! He's mean, but I still love him! If we aren't allowed to chose pets, I'd say my Hope chest. DH bought it for me for Christmas a few years ago and it's filled with everything that is special to us... our Wedding pictures and videos, things left to me by my Grandma who has passed away, reminders of special days that DH and I have shared together etc... If there were ever a fire in our home (god forbid), I'd grab the cat, throw him in the hope chest and drag the whole darn thing outside with me!
