FAQs
How much food should a cat eat daily?
A typical 10 lb adult cat needs about 7-8 oz of wet food or 1/2 cup of dry food per day. Always verify with your specific brand’s calorie content using our food calorie calculator.
How do I measure cat food accurately?
Use a digital kitchen scale for grams — it’s more accurate than cup measurements. Alternatively use a standard measuring cup but avoid packing the kibble.
