How We Test

Our promise is simple: we quantify what matters—odor, tracking, noise, and clean‑up time—so you can build a cat‑approved, low‑fuss setup with predictable results. Here’s exactly how we measure and score.

Test Environment and Samples

Spaces: We run tests in a controlled 8×10 room that simulates a typical bathroom/laundry, plus real‑home validations in apartments and multi‑cat households.
Cats: A diverse panel including large/high‑peeing cats, timid cats, and seniors validates behavior fit and access.
Procurement: We purchase most products. When manufacturers provide samples, we disclose it and apply the same procedures without preview or approval rights.

Odor Containment (VOC/Ammonia Proxy)

Instruments: VOC sensors near the box rim and at 1 meter, logged over time. For urine odor proxy, we monitor ammonia with appropriate safety limits.
Protocol: Standardized deposits (synthetic waste or controlled littered waste), consistent room ventilation, timed readings at 5, 30, 120 minutes, and 24 hours.
Output: A normalized Odor Score that rewards lower peaks and faster return to baseline; we note filter media or enclosures that actually move the needle.

Tracking and Scatter

Method: Pre‑weighed mats and controlled floor sections capture scatter. We measure mass gain and count trackback events across a fixed walkway.
Stressors: We include fast exits, high‑energy digs, and multi‑cat sequences to simulate real‑world mess.
Output: Tracking Score favors low scatter mass and fewer trackback counts; we verify results with different litters and mat textures.

Noise and Vibration (for Automatic Units)

Instruments: Calibrated decibel meter at 1 m and 3 m; accelerometer on adjacent surfaces.
Protocol: Measure startup peaks, average cycle levels, and late‑night quiet‑hour performance.
Output: Noise/Vibration Score reports dB(A) ranges and surface‑borne vibration risk for neighbors and light sleepers.

Time to Clean and Ease of Maintenance

Procedure: Timed daily scoop or cycle reset, plus weekly deep clean including disassembly, washing, drying, and reassembly.
Metrics: Minutes per day and per week, parts count, crevice/soil traps, and residue after rinse.
Output: Maintenance Score rewards fewer parts, faster routines, and materials that release waste without scrubbing.

Behavior‑First Fit and Safety

Access: We evaluate entry height, internal footprint (minimum 1.5× cat body length), and turn‑around clearance for large and senior cats.
Privacy vs. Visibility: We observe acceptance with covered vs. open designs and record avoidance triggers.
Automation Safety: We test sensor reliability, jam handling, pinch protection, and manual fail‑safes. Units that cycle with a cat nearby are disqualified.

Scoring and Weights

Core Weights: Odor (30%), Tracking (25%), Maintenance (20%), Behavior/Safety (15%), Noise/Vibration (10%; manual boxes scored N/A).
Kits and Use‑Case Adjustments: We publish variants (e.g., small‑space, senior, multi‑cat) with transparent weight tweaks relevant to the scenario.

Repeatability and Controls

Replicates: Minimum three runs per metric; we report averages and note outliers.
Controls: Standard litter baselines, consistent fill depths, and fixed room conditions.
Limitations: Real cats vary; we disclose where behavior or environment may influence outcomes.

Real‑Home Validation

We deploy top picks in active homes for at least two weeks, tracking odor trend lines, cleaning time, and cat acceptance. When lab and lived results diverge, we investigate and update guidance.

Updates and Versioning

We re‑test after major redesigns, filter media changes, or meaningful firmware updates. Each guide shows a revision date and what changed.

Ethics and Welfare

Cats are never forced to use a product. We retire any unit that causes distress or poses safety risks. Our goal is stress‑free, consistent box use—never shortcuts at your cat’s expense.
