Vittles Vault Outback Stackable 40 lb Airtight Pet Food Storage Container Review (2026)

What you get

Vittles Vault's Outback 40 lb container is made by Gamma2, an established name in pet and livestock feed storage, and this size holds up to 40 pounds of dry feed depending on the density of what is stored. Retailer listings put its dimensions at roughly 12 by 20.5 by 17 inches, giving it a tall, stackable shape rather than a wide, squat footprint, which matters if floor space in a feed shed or garage is limited. A scoop is included with the container, according to PetSmart's product listing, which saves keepers from having to buy or dig up a separate scoop before the container is even in use.

The sealing system

The lid uses Gamma2's patented spin-on Gamma Seal Technology, a threaded locking ring with double gaskets that locks down with a quarter turn rather than needing to be pried or snapped into place like many bucket lids. That design is meant to keep the contents airtight between uses, cutting down on the stale smell and moisture pickup that loose-lidded bins can develop over time, and it also makes the container harder for insects to get into compared with an unsealed feed bag. Because the lid threads on rather than snapping, it holds up to repeated daily opening and closing better than lids that rely on flexible plastic tabs, which can crack or lose their grip after months of use.

Material and durability

Retailer listings describe the container as BPA-free plastic, built and assembled in the USA, and Amazon's own listing for this item lists the material as polyethylene terephthalate; either way, it is a rigid plastic rather than metal, so it will not dent but can crack under severe impact the way a metal trash can would not. That plastic build is not fully rodent-proof against a persistent chewer, since determined rodents can gnaw through plastic given enough time and motivation, so keepers dealing with an active rodent problem may want to store it inside a shed or add a metal outer container for extra protection. For general pest and moisture protection in a garage or feed room, the sealed lid and rigid walls are more than adequate.

Stacking and storage space

The stackable shape is the main selling point over a standard round bucket, since two or more Vittles Vault containers of matching sizes can sit directly on top of each other, letting keepers store several feed types, like layer feed and scratch grains, in a smaller footprint than side-by-side bins would need. This works especially well in a garage corner or feed shed where floor space is at a premium but vertical space is available. Buyers using larger bulk feed bags, such as 50 pound sacks that do not fit a 40 lb-rated container, should size up to Vittles Vault's larger option rather than trying to overfill this one.

Who this size fits

This container suits keepers who buy standard 40 lb bags of chicken feed and want an airtight, stackable, made-in-USA option backed by an established brand, with a scoop included so it is ready to use out of the box. It is a weaker fit for keepers battling an active rodent problem, who may need a metal can instead, or for anyone buying larger 50 lb feed bags, who should look at Vittles Vault's bigger size. For typical backyard flock feed storage, it is a solid, low-maintenance option that just needs an occasional wipe-down to stay clean.
