Ann initially thinks the animals in the Valley are probably the last of their species; however, at the end of the book Loomis reveals he has seen birds flying in the distance west of the valley, which implies other life as well. There are rabbits and squirrels in the valley. There are also some crows, which Ann believes survived because only they had the "sense" to stay in the valley, while other birds migrated. There are two cows, a bull calf, and chickens on Ann's farm. Finally, there is the dog, Faro, who belonged to Ann's cousin David.
