A pet food composition comprising:

• from about 5 g/1000 kcal to about 80 g/1000 kcal of a fat, the fat comprising one or more medium chain triglyceride, wherein at least one medium chain triglyceride comprises an octanoate component, the medium chain triglyceride comprising the octanoate component comprising about 7% or more of the total weight of fat in the pet food composition;
• from about 40 g/1000 kcal to about 150 g/1000 kcal of a protein;
• optionally, from about 5 g/1000 kcal to about 55 g/1000 kcal of a fiber;
• and
• optionally, from about 3 g/1000 kcal to about 130 g/1000 kcal of a carbohydrate,
• wherein all metabolizable energy amounts are based on the total metabolizable energy of the pet food composition.

A feline food composition comprising:
