My dog gets very defensive if he can see/hear someone (especially if it's someone with a dog) but not get to them. For some reason, it helps a lot if we simply open the windows in the car.
My crested gecko doesn't like to eat crickets once they get to the point where they develop wings - which is really annoying, because that's also the point at which they start to chirp.
My cat (who passed in May) loved to lick apple cores, and eat raw pumpkin.
