Fit & travel readiness

Know before you buy—or fly.

Check pet products against real measurements, published rules, and clearly labeled evidence. No “approved” badge without the limits behind it.

Official

Official exact-SKU claims, reviewed public reports, and rule-based estimates stay visibly separate.

Choose exact models. We’ll show the rule, evidence strength, and what remains untested.

What a result means

The answer includes its uncertainty.

Product compatibility is not a single green check. We separate the maker’s rule, our class-level inference, exact-product testing, and reports from real homes.

Read the evidence method
  1. A
    Official

    Published boundary

    What the machine or product maker currently says, with a dated source.

  2. B
    Tested

    Controlled observation

    Bench cycles and real-use tests following a repeatable protocol.

  3. C
    Community verified

    Independent use

    Three or more complete reports that agree under comparable conditions.

  4. D
    Single report

    Useful signal, limited sample

    One or more reviewed exact-pair reports, without enough consistent evidence to generalize.

  5. E
    Estimated

    Useful, but provisional

    A rule-derived starting point that stays out of search until reviewed.

Built for difficult decisions

We show the line, not just the label.

Every rule has a source

Official wording, access date, and conflicts stay attached to the result.

Unknown is an honest answer

Missing particle size or contradictory policy produces a condition, not false certainty.

One engine, four checks

Released in evidence order.

Each module launches only when its data is deep enough to improve the decision.
