The most accurate way to measure homemade cat meals is by using a digital kitchen scale in grams rather than relying on volume cups, because nutrient and calorie density can vary significantly across ingredients. It is also essential to use a balanced recipe formulated by a veterinary nutritionist to ensure your cat receives all necessary amino acids, vitamins, and minerals. What has worked best for many owners is weighing out individual daily or weekly portions in advance and storing them in airtight containers in the fridge or freezer.
