First thing I would grab is my phone. To browse internet nowadays, that's what I mostly use. It's small, light, and very easy to carry—all of that makes it extremely comfortable to use. I'd take my tablet, too, as well as my 3DS. I would take my laptop, but it'd take me some time to unplug the charger and all, so I'd just leave it there. I have a cat, but don't need to worry about her. She's quite smart, so she could get out of the house herself without any help. (:
