The prototype at a glance
21.65 × 13.78 inApproximate footprint · 3.15 in overall heightPrototype specifications; production tolerances are not finalized. Watch the actual sample being handled below.
Actual prototype · Hands-on demonstration
A 48-second continuous excerpt supplied by the project owner shows the cardboard inserts being lifted and fitted by hand, without tools.
The insert is lifted and repositioned in the tray.
The insert comes out, revealing the wooden frame.
Another insert is brought into position and fitted by hand.
Cropped and brightness-adjusted real footage. Original speed, no cuts within this excerpt, audio removed. The frame is handled and repositioned; this is not a stability or force test. These samples do not guarantee fit across future production batches. Flip-fit after the trial remains a separate owner-reported check.
What has actually been tried
A multi-cat household used the same side of one insert for seven days. The owner reported daily scratching, cats resting on the board, little loose debris, and little movement with a cat on it.
The project owner then confirmed that the used insert could still be removed and flipped by hand, and the spare insert fitted normally.
One household, not a controlled comparison. The larger cat was estimated by its owner at 16.5 lb (7.5 kg), not independently weighed. No lifespan, odor-safety or all-floor stability claim is made.


Designed around replacement
The prototype’s two supplied inserts could be exchanged by hand. Future refill availability and final fit specifications are still being verified.
The used insert flipped and fitted normally after the seven-day trial. The reverse side has not completed an equivalent wear test.
The main structure remained functional in the short trial. Long-term durability and resistance to chewing have not been established.
