I have three cats. I'd take two and leave the one that pisses behind. The fish and lizards would have to stay. The pillow would have to come along too along with the digital camera with media. I don't have any personal attachments to any of my other belongings, so whatever utilitarian items (clothing, shoes, etc) I come across would be the rest. Throw the bike rack and bike on the back and drop off all the library books and done!
Stuff can be replaced. Being alive and safe cannot. I'm glad it was just a fire drill for you.
