How many cans of cat food should I feed per day?

It depends on your cat's weight and the caloric content of the food. For a 4 kg adult cat needing about 237 kcal daily, if the canned food provides 85 kcal per 100g, approximately 280 grams (about 1.6 standard 170g cans) are needed per day. Use the RER formula for precise calculation.

How long can opened canned cat food last?

After opening, transfer to a sealed container and refrigerate. Consume within 48 to 72 hours. Do not leave at room temperature for more than 1 to 2 hours to prevent bacterial growth.
