Historically we have fed our pet cats from bowls, but we now understand that this does not meet the cat’s instinctive, natural feeding needs. As humans we naturally want to feed the people and animals that we love, and like to see an empty plate! Just because your cat doesn’t finish their bowl at the first sitting, does not necessarily mean that they don’t like the food.
It is normal for cats to pick at their food throughout the day (and night!).
Cats are predators, tending to eat little and often in their natural environment, hunting 10-20 times a day.
