Complete and balanced
The voluntary Australian Standard (AS 5812-2017) for the Manufacturing and Marketing of Pet Food sets out guidelines for how pet food should be labelled. One key feature to look for on a label is whether a product provides a complete and balanced diet for your pet at a particular life stage.
Look for a statement about nutritional completeness which references AAFCO (the American Association of Feed Control Officials). This indicates that the food is designed to provide all the nutrients that your cat needs, and in the right quantities, as outlined by the AAFCO requirements.
Please note that food produced in Europe may refer to FEDIAF (The European Pet Food Industry Federation).
