This is very common for predators as they may go several days between kills. They have to eat when they can as there is no guarantee of when the next meal will be. For that matter, it is not unusual for other animals, including humans. I am certain that an evolutionary drive to eat when food is available is a major factor behind rush obesity rates. We evolved with food shortages.
