Frequently Asked Questions
How long does 1 kg of cat food last?
A 1 kg (1000g) dry food bag lasts around 40 days for a low-activity cat eating 25g/day, and about 16-17 days for an adult cat consuming 60g daily.
Are 10 kg or 15 kg bags practical for a single cat?
For a single cat, 10-15 kg bags stay open 5 to 8 months, causing fat oxidation and staleness. Large bulk bags are best suited for multi-cat homes or airtight container storage.
How quickly should an opened cat food bag be consumed?
Once unsealed, dry kibble is best consumed within 4 to 6 weeks (30 to 45 days) to minimize vitamin degradation and lipid rancidity.
