What are the Ferret Nation 182 measurements?
Petco lists 91.44 × 63.5 × 158.75 cm (36 × 25 × 62.5 in). Multiplying the two base measurements gives 5,806.44 cm² (900 sq in). That is 107.53% of the floor figure used here. This multiplication is ours; it does not turn an outside footprint into usable inside room.
Stand is included in listed height. Usable inside height is not sourced, so a dimensional pass remains provisional. Bar spacing must be checked. Do not subtract a guessed wall thickness or assume a stand is a standard height. If the measurement basis is not stated, keep it unknown until the enclosure itself has been measured. The shortest usable width, depth and living height are the figures to enter in the checker.
| Check | This model | Our comparison |
|---|---|---|
| Continuous base area | 5,806.44 cm² (900 sq in) | 5,400 cm² (837 sq in) |
| Living height | 158.75 cm (62.5 in), recorded height | 120 cm (47.24 in) inside |
| Base shape | 91.44 × 63.5 cm (36 × 25 in) | 90 × 60 cm (35.43 × 23.62 in), either way round |
How many rats does this size suit?
The recorded envelope reaches the tier for up to 5 rats. This is conditional on the usable inside dimensions reaching every figure, not a confirmed stocking capacity.
For rats, this comparison uses the larger figures selected by our existing rat calculator: 90 × 60 × 120 cm (about 35 × 24 × 47 in) for two to five, and 93 × 63 × 123 cm (about 37 × 25 × 48 in) for six to ten. Our cage guides also discuss smaller Woodgreen recommendations. These are different published recommendations, not a formula we can combine into a per-rat allowance.
The height means living space, with the stand left out. Shelves, hammocks and routes between them make that height usable, but they do not repair a narrow base. Check where the lowest living tray starts and where the roof ends. An advertised double unit may have a substantial stand and a full-width divider within its total height.
Rats need company. The comparison starts at two, and it does not stretch the ten-rat tier into a capacity for eleven or more. A bigger group needs an individually planned home rather than a number obtained by dividing cage volume. Doors must also let you reach resting areas, water points and the back corners without dismantling the whole arrangement.
The underlying number comes from our rats cage-size guide. Where that guide gives different source figures, we state which comparison we use rather than merging them. In the checker, an unsupported group size produces no capacity answer. That is more useful than a precise-looking number made by extending a rule that was never written for that group.
Are the bar gaps narrow enough?
The accepted specification gives Not established in the accepted specification. Our guide uses 10 mm (0.39 in) or less for this profile. Check the actual empty gap, not the distance from the centre of one wire to the next. A gap inside the numeric limit is only one part of checking the enclosure.
A missing number means it has not been established, not that there are no openings. Solid-sided enclosures still have lid mesh, ventilation slots and door joins. Inspect those separately, including any place changed by a bottle fitting or a replacement panel. If a listing contains conflicting bar measurements, use a direct measurement or ask the seller for the exact version rather than picking whichever value makes the result pass.
What should you check about doors and levels?
Open every access door and check that you can reach the lowest and highest living areas for cleaning and daily checks. Look at catches, corners and the gap around each door, not only the long side panels. A large outer footprint does not show how a fixed partition, sloping wall or deep tray changes the usable space inside.
The source records the levels as 2. Platforms and upper floors are extras in this base-area calculation. If a divider makes two separate homes, compare each side on its own. If the cage has a stand, storage shelf or raised legs, those are not living height. Check ramps and landing routes after equipment is in place, not just in an empty product photograph.
How to check your own enclosure
- Confirm the exact model. Match the model name and version to the source. Similar names, different sizes and add-on units are not interchangeable. Keep the maker specification beside your measurements.
- Measure the main floor inside. Measure wall to wall across the usable base, in centimetres or inches. Use the narrowest usable part where sides taper. Do not include roof overhangs, wheels, legs or an external shelf.
- Measure living height. Start at the living floor, not at the bottom of the stand. Where storeys are divided, note the clearance in each. A single total outside height cannot describe all those spaces.
- Check every opening. Measure the empty gap at bars, doors, corners and lid mesh. Record a missing figure as unknown. Inspect fitted accessories for new gaps rather than relying on the original panel specification.
- Run the inside comparison. Use the same animal, group and profile here, then enter the measurements you took. Compare floor shape and height as well as area. Read the next checks even if the size result reaches the figures.
Open the cage checker with Ferret Nation 182 and rats selected. You can switch to inside measurements when you have measured the actual enclosure. The checker accepts inches as well as centimetres, and its comparison link keeps the selected animal and model.
Which larger models could you compare?
These are larger recorded-size candidates from the same catalogue, not endorsements. Their inside measurements, openings and layout still need checking.

Common questions
Is the MidWest Ferret Nation 182 big enough for rats?
On its listed dimensions, the MidWest Ferret Nation 182 reaches our size figures for 2 rats, but usable inside space still needs checking. Use the recorded measurements as a starting point, then compare actual inside width, depth and living height. The result does not assess every opening, door or furnishing.
Does extra height make up for a small floor?
No. We check floor area, base shape and height separately. A narrow, tall enclosure can have a large volume while missing the base dimensions in our guide. Upper levels, tubes and shelves are not added to the continuous ground floor in this comparison.
Are these inside or outside measurements?
The accepted specification is recorded as outside. Unless a source explicitly identifies usable inside space, we do not relabel it as inside. Measure the actual living base and height, leaving stands and roof overhangs out, before relying on a positive size result.
What if the bar spacing is not listed?
Treat it as unknown, not a pass. Our guide uses 10 mm (0.39 in) or less for this profile. Check the empty gap between wires, plus door joins, corners, mesh and ventilation slots. A solid wall does not remove the need to check openings elsewhere.
Can I use the checker with measurements in inches?
Yes. Choose inside measurements and inches, then enter width, depth and living height. Bar gaps are entered separately in millimetres. The checker converts the dimensions to centimetres before applying exactly the same floor and height figures, and shows both units in the result.
What does a model’s sold-for list tell me?
It tells you how the maker or retailer describes the product, not whether it meets the figures we use for that animal. We keep that marketing description separate from the arithmetic. Model versions, usable inside space, group needs and access all still need checking.
