Pet food compositions

A pet food composition comprising:

• about 20 wt. % or more of fat comprising one or more medium chain triglyceride, wherein at least one medium chain triglyceride comprises an octanoate component, the at least one medium chain triglyceride comprising the octanoate component comprising about wt. % or more of the fat, based on the total weight of the fat on a dry matter basis;
• a protein;
• and
• a fiber;
• wherein the pet food composition comprises about 10 wt. % or less of carbohydrate and about 5 wt. % or less of digestible starch,
• wherein the pet food composition has a ketogenic ratio of about 1.5 or greater as calculated from Formula 1:
• (0.9 F+0.46 P)/(0.1 F+0.58 P+C), wherein F is the weight percentage of fat, P is the weight percentage of protein, and C is the weight percentage of carbohydrate, and all weight percentages are based on the total weight of the pet food composition on a dry matter basis.

A pet food composition comprising:

• from about 20 to about 60 wt. % of fat comprising one or more medium chain triglyceride, wherein at least one medium chain triglyceride comprises an octanoate component, wherein the at least one medium chain triglyceride comprising the octanoate component comprises about 10 wt. % or more of the fat, based on the total weight of the fat on a dry matter basis;
• from about 15 to about 55 wt. % of protein;
• from about 10 to about 60 wt. % of a fiber;
• and
• one or more fatty acid,
• wherein the pet food composition comprises about 10 wt. % or less of carbohydrate and about 5 wt. % or less of digestible starch, and wherein all weight percentages are based on the total weight of the pet food composition on a dry matter basis.
