What unusual habits have your pets had?

My dog is a rescue so some of her habits might come from unpleasant experiences, but she is a delightful little weirdo. She hates walks, only uses them to go to the bathroom and will then immediately start trying to get into any nearby or remotely available car. She will also poo herself inside out outside for any amount of time, like she feels she won't be allowed back inside until everything is out of her. She likes company for drinking, and will wait to be escorted to her water bowl. The only exception for this is if I put socks on and am therefore obviously going out, and then she will try to drink all of the water in the world, even though she's coming too. She likes her treats in order, if they're given in the incorrect order by a fool who doesn't know then she'll just sit with the wrong one until its corrected. At my house she happily gets herself on the sofa or bed whenever she wants, at my friend's house she'll stand waiting at them until she's given express permission to get on. Not by me, my permission doesn't count, my friend has to tell her. She finds arguing relaxing, as soon as someone gets het up about something, just venting about something silly on telly etc, she'll immediately be asleep and snoring. She doesn't bark at all, for anything. If she gets really excited you might get one lone pathetic attempt at a single woof. In her dreams though she does sleep barking all the time. It's so adorable, that and the little flippy feet. Absolute loon.
