Stack & Shift | Stacking & Foraging Cups

Built to be messed with 

Stack them. Nest them. Hide something tasty between them. Then hand them over and watch your little architect completely disregard whatever arrangement you had in mind. Stack & Shift turns a simple set of stacking cups into an enrichment activity made for curious paws and noses. Stack them into a tower, nest them together, turn them upside down or tuck a little forage between the layers and see what your little one decides to do with them. The design has been safely adapted from stacking toys originally created for human babies, bringing that same considered approach to materials and construction into a piece of enrichment for rabbits, guinea pigs and other suitably sized small furries. 

For The Mason, that open-endedness is exactly the point. These are the little rearrangers who like to push, move, investigate and make changes to their surroundings. Stack & Shift gives them something they’re actually allowed to reorganise — whether they’re separating the cups one by one, knocking down your carefully constructed tower or hunting for something tasty tucked between the layers. There’s no single way to play, either. Build them high, spread them around, nest them together or turn them upside down and add food. Tomorrow, set them up completely differently and let The Mason get back to work.

❓ FAQs

Q: Which Play Personality is Stack & Shift best for?

A: We’ve chosen it for The Mason — the little rearranger of The Every Tail Play Personality System®. If yours is forever shifting things, investigating their setup or deciding something would be much better over there, Stack & Shift gives those busy instincts somewhere to go.

Q: How can I use the cups for enrichment?

A: There are loads of options. Hide a little food beneath an upside-down cup, place pieces between stacked layers, nest cups together with something tempting inside, build a tower for them to dismantle or scatter the cups around their space for them to investigate individually. Change the setup every so often and the same cups can become a slightly different activity each time.

Q: How have Stack & Shift been adapted from human baby toys?

A: The original design comes from stacking toys created for human babies and has been safely adapted for small-furry enrichment. We loved the simplicity of the design: chunky cups that can be stacked, nested, separated and moved around in all sorts of ways. They should still be used as an enrichment toy rather than a chew toy, with play supervised and the cups removed if they become damaged.

Q: What animals can use Stack & Shift?

A: They can be used as enrichment for rabbits, guinea pigs and other suitably sized small furries who enjoy interacting with and rearranging objects. Always choose a set and activity appropriate for your individual animal.

Q: Can I put food inside the cups?

A: Yes. That’s one of our favourite ways to use them. Add a little of their usual food, forage or an appropriate treat beneath or between the cups and let them work out how to reach it.

Q: Do all four sets contain the same cups?

A: No. Stack & Shift comes in four set variations, with different cup quantities, sizes and colour combinations. Check your chosen option before ordering so you know exactly which stack is coming home.

Q: Are Stack & Shift chew toys?

A: No. They’re designed for stacking, foraging and interactive enrichment rather than chewing. If your little one begins heavily gnawing or damaging the cups, remove them and offer something specifically intended for chewing instead.

Q: Should I supervise play?

A: Yes. We recommend supervised enrichment and checking the cups regularly for signs of wear or damage. Remove any damaged pieces from use.
