Final answer:
The closest correct daily maintenance energy requirement for a 4 kg cat, based on veterinary nutrition guidelines, would be approximately 220 kcal; therefore, option B. 220 kcal is the most accurate choice given the average values.
Step-by-step explanation:
The daily maintenance energy requirement (kcal) for a 4 kg cat is not explicitly provided in the provided references. However, a rule of thumb in veterinary nutrition is that an average indoor pet cat might require anywhere from 20 to 30 kcal per pound (45 to 65 kcal/kg) per day to maintain body weight. For a 4 kg cat, that would translate to an energy need of 180 to 260 kcal/day. Therefore, the closest correct option, based on average values, would be B. 220 kcal.
Energy requirements can vary based on a cat's age, activity level, and metabolism. Cats may also have different maintenance energy requirements than humans or other animals due to their specific physiological needs. Generally, smaller animals like cats have a higher metabolic rate per body weight compared to larger animals. It's essential to create a dietary plan that is suited to an individual cat's needs.
