George is a Macedonian tortoise. On a recent holiday to northern Greece, with my son, I was lucky enough to meet some of George's relations living in the wild.
George, as with young children, has his own daily routine. He wakes-up at the same time everyday, has lunch at 12 noon, and goes to bed at the same time every evening. He also explores the garden following the same route in a ritualistic way.
Animals, like humans, prefer a predictable life style to avoid stress and to be happy.
