The picks
★Best for big bags
Gamma2Vittles Vault Outback
Best for: Garage or outdoor storage
A square HDPE container with a spin-on Gamma Seal lid in 30, 50 and 80 lb sizes. Petmate says it is food-safe, BPA-free and will not shatter if dropped.
What we like
- Airtight, pest- and water-resistant seal
- Large sizes
Watch out for
- Spin lid is slower to open
- Wash it regularly: oils can go rancid (maker)
The Outback is a square container with Gamma2’s spin-on threaded lid and gasket seal. It comes in sizes holding up to 30, 50 or 80 lb; the 50 lb model measures 14 x 14 x 20 in. Petmate says it is made of food-safe, BPA-free plastic that will not shatter or crack if dropped, and it meets FDA food-contact rules. It has molded handles, a scoop and stacks. Petmate says it is made in the USA and recommends regular washing, because oils soak into plastic and can turn food rancid.
★Best for kitchens

Watch out for

IRIS calls this 33 qt model a 30 lb container, though capacity varies by food. It measures 16.5 x 10.8 x 18.62 in, has snap-lock latches and a translucent body so you can see the food level. A 1-cup scoop and a set of wheels are included. IRIS warns it is a suffocation hazard: do not let children or pets play inside it.
★Best for small bags
IRIS USAWeatherPro Airtight Pet Food Container, 15 Qt
Best for: Cat food and treats
A 15 qt WeatherPro container that IRIS rates for up to 13 lb of dry food.
What we like
- Small footprint
Watch out for
- Small bags only
The 15 qt WeatherPro model is rated for up to 13 lb of dry food, which suits cat food or treats. IRIS describes its WeatherPro range as airtight. See the maker page for its dimensions.
How to choose
- Keep the bag. Put the original bag inside the container so you keep the lot number. See pet food storage safety.
- Size up. Capacity depends on kibble shape.
- Wash it between bags. Oils build up in plastic.
- Read the label first. Our guide to reading a pet food label explains what the bag tells you.
Frequently asked questions
Should I pour kibble straight into the container?
The FDA recommends keeping dry food in its original bag, which has the lot number and best-by date. You can put the whole bag inside the container. See our pet food storage safety guide.
Will a 30 lb container hold a 30 lb bag?
Not always. Makers say capacity depends on kibble shape and density. Petmate suggests rounding up to the next size if in doubt.
How often should I wash the container?
Petmate recommends washing and drying it regularly, because oils absorb into the plastic and can turn food rancid.
Can I store it in the garage?
Petmate says the Vittles Vault Outback can be kept in a garage, barn or backyard.
