I just returned from a three-day trip that was originally supposed to be a one day trip. One result: my chinchillas were very hungry.
So, one of the first things I did upon returning home was to go feed them. As usual, upon opening the top door to their cage Mario ran for cover (hiding near the bottom) and Luigi, who had approached the door upon hearing me enter the room, instinctively froze so as not to attract predators. I gave Luigi a little pet, announced that dinner was served, and placed the food in the center of their “hidden” (read: safe) room and began to close the door.
As the door was swinging shut, Luigi started heading for the food and I realized I’d forgotten to check their water so reopened the door at which point Luigi stepped back away from the food and once again froze next to the opening.
How ridiculous is that? He was clearly hungry, and clearly not afraid of me, but despite the presence of food he went back into “don’t let the predators see you moving mode”.
