In a natural wild environment, cats are hunters, spending many hours of the day looking for and capturing food. With many more unsuccessful hunting attempts than successful, hunting is a very time and energy consuming activity.
Living as part of a household, cats become accustomed to eating twice a day. They enjoy the comfort of you doing the hunting on their behalf. As a result, they experience less stimulation and activity normally associated with eating.
Additionally, a cat’s digestive system is designed to take in multiple small meals throughout the day rather than two meals in twenty-four hours. Often cats learn to consume larger quantities in one or two sittings because they come to realise that food is not available at other times, but their natural instinct is to eat smaller amounts more often.
