Alternatives to the Ferret Nation
What the Ferret Nation is known for, the one specification MidWest will not publish for it, and three cages that match it on the rest.
If you are looking for an alternative to the Ferret Nation 182, buy the MidWest Critter Nation Double Unit (162): it is the same chassis from the same manufacturer with the same double-locking doors and the same two storeys, and MidWest does publish its bar spacing — half an inch — which it does not for the Ferret Nation. The budget pick is the Critter Nation Single Unit (161), which has identical hardware and bar spacing in one storey, clears VCA's published cage figure comfortably, and takes the second unit later if you add a ferret. The Prevue 485 Feisty Ferret is the pick if the Ferret Nation's footprint is the problem rather than its price. We have left the Ferret Nation 182 itself on the page so you can compare it directly. Prices are live with an as-of date under each button.
Search Console shows "ferret nation cage size" as the best striking-distance query on this property outside the fish-tank cluster, with "ferret nation cage dimensions" close behind. People arrive looking for this cage's numbers. Our review of the 182 gives them; this page says what else will do.
What the Ferret Nation is known for
Three things, and all three are real. It is the two-storey ferret cage, with the full-width double doors that make the whole interior reachable instead of making you fish through a hatch. Its shelves are solid and sit on a lip rather than clipping on, which is the right arrangement for an animal with a ferret's feet. And its latches are double-locking, which is the specification that actually stops escapes — best escape proof cages explains why the door matters more than the bars.
Ferret cage suggested minimum · suggested minimum
24in x 24in x 18in high (60cm x 60cm x 45cm)
Our conversion: 576 square inches, or 4 square feet, of floor
On VCA's published figure the 182 is not merely adequate but several times over it, which is true of its Critter Nation sibling too. So floor area is not what separates these cages, and a comparison built on floor area would be telling you nothing.
The one thing it does not publish
MidWest publishes no bar spacing for the Ferret Nation anywhere we can find, and its retail listing states a figure twice, differently — one inch in a product attribute and half an inch in a feature bullet. Those are not the same cage. We recorded that finding in the review rather than picking the number we preferred, and it is the honest reason to consider the Critter Nation instead: same maker, same chassis, one published figure.
To be clear about what that is and is not: it is a documentation problem, not a safety finding. We have no evidence that the 182 as built has a bar spacing problem, we have not measured one, and nothing here claims a defect. What we cannot do is cite a specification for it, and on a site that cites every figure it prints, that matters.

|---|---|---|---|
| Critter Nation 162 | Two storeys, full-width double doors, double-locking latches, solid shelves | A published bar spacing of 0.5 in, which the 182 does not have | Nothing structural; the two are siblings |

Dimensions as published by each manufacturer or its retailer, read 27 September 2026 and linked in each assessment below. A tick marks a product that clears our own floor-area threshold; a cross marks one that does not. Where a manufacturer does not publish a figure, the cell says so rather than estimating it.
Which to buy
- Two or more ferrets, and you want the Ferret Nation experience with a published bar spacing: the Critter Nation 162.
- One or two ferrets, and the 182's price is the obstacle: the Critter Nation 161. It clears VCA's figure several times over and expands later.
- The footprint is the obstacle: the Prevue 485. Smaller, cheaper, and worth a carabiner on each door — see best escape proof cages.
- You already own a 182: keep it. Nothing on this page is a reason to replace a cage you own, and ferret nation against critter nation sets out how close the two really are.
- You want more height than any of these: none of them is the answer, and the published ferret figure does not ask for it. Best multi-level cages covers what height actually buys a ferret.
Our pick · Ferrets of any age, and kits especially
MidWest Critter Nation Double Unit (162)
The half-inch bar spacing is the whole argument: it is the same cage as the Ferret Nation with a gap a ferret kit cannot get its head through.
- Dimensions
- 36 x 24 x 63 in including the rolling stand
- Continuous floor
- 36 x 24 = 864 sq in (6 sq ft) per level, two levels
- Bar spacing
- 1/2 in horizontal
- Material
- Powder-coated steel with deep removable plastic pans
- Levels and ramps
- Two levels with a locking swing-up ramp and full-width doors
What it gets right
- 1/2 in bar spacing holds a kit that 1 in spacing does not
- 6 sq ft of usable floor per level, comfortably over our per-level bar
- Full-width doors mean you can reach every corner, which matters weekly
- Deep pans contain litter rather than spreading it
What it gets wrong
- Horizontal half-inch bars give less climbing purchase than wider spacing
- Heavy and awkward to assemble alone
- The stand's casters roll on hard floors more than you want them to
Who should buy something else
Not necessary if your ferrets are adults and you have measured their head width against 1 in. The Ferret Nation costs less and climbs better; the half-inch is insurance you may not need.

Number 2 · A single ferret, or a first half of a double
MidWest Critter Nation Single Unit (161)
The same 6 sq ft floor and the same half-inch bars in one level, which is the right buy only if you are certain you will add the second unit.
- Dimensions
- 36 x 24 x 25.625 in for the cage section
- Continuous floor
- 36 x 24 = 864 sq in (6 sq ft), one level
- Bar spacing
- 1/2 in horizontal
- Material
- Powder-coated steel with a deep removable plastic pan
- Levels and ramps
- One level, with a shelf; a second unit stacks on top later
What it gets right
- Identical 1/2 in bar spacing safety
- 6 sq ft of usable floor
- Cheaper entry point, and the 162 upper unit fits it later
What it gets wrong
- One level gives a ferret much less vertical variety than two
- Buying the single then upgrading costs more than buying the double outright
Who should buy something else
Wrong for two or more ferrets. One level of 6 sq ft is enough floor and nowhere near enough structure for a pair that will spend their waking hours in it.

Number 3 · A smaller room and a single adult ferret
Prevue Pet Products Feisty Ferret Home 485
A cheaper multi-level cage whose 4.3 sq ft per level and 7/8 in bars both land below the standards we apply, which is the honest reason it is last here.
- Dimensions
- 31 x 20 x 54 in with the stand, 41.5 in high without it
- Continuous floor
- 31 x 20 = 620 sq in (4.3 sq ft) per level
- Bar spacing
- 7/8 in
- Material
- Powder-coated wire with removable platforms, grille and debris tray
- Included fittings
- Ramps, shelves and a hammock supplied
What it gets right
- Fits a 31 in footprint where the MidWest cages need 36 in
- Hammock, ramps and shelves included
- Removable grille and tray make cleaning straightforward
What it gets wrong
- 620 sq in per level is 28 percent less than the Critter Nation
- 7/8 in bar spacing is close enough to 1 in to carry the same kit risk
- Lighter gauge wire than the MidWest and Savic cages
Who should buy something else
Not for kits, not for two ferrets, and not if you can fit a 36 in cage. It solves a space problem and does nothing else better.

Number 4 · Adult ferrets that climb
MidWest Ferret Nation Double Unit (182)
Slightly more floor per level than the Critter Nation and a one-inch bar gap, which is fine for a grown ferret and the reason kits escape.
- Dimensions
- 36 x 25 x 62.5 in including the rolling stand
- Continuous floor
- 36 x 25 = 900 sq in (6.25 sq ft) per level, two levels
- Bar spacing
- 1 in
- Material
- Powder-coated steel with deep removable plastic pans
- Levels and ramps
- Two levels with locking swing-up ramps and ramp covers
What it gets right
- 6.25 sq ft per level, marginally more than the Critter Nation
- 1 in bars give much better climbing purchase
- Same full-width doors, deep pans and locking ramps
- Usually cheaper than the equivalent Critter Nation
What it gets wrong
- 1 in spacing is the single reason ferret kits get out of this cage
- No way to retrofit narrower spacing; the fix is a different cage or wire panels
Who should buy something else
Never for kits, and not for a small jill who can flatten her head through a one-inch gap. Measure the animal, not the marketing, and buy the Critter Nation if there is any doubt.

What this page does not claim
No veterinary or welfare body publishes a bar spacing, a latch standard or a shelf specification for ferrets; VCA publishes a cage size and nothing else relevant here. Every product figure above is the manufacturer's own, cited at the point of use, and where a manufacturer publishes nothing or contradicts itself this page says so rather than choosing a number.
