Comparable geometry, finally
SC09 is not simply bigger than SC10.
SC09 is larger by enclosed cabin volume and exterior width/depth. SC10 is the longer machine, has a 500 mm open bed, unlimited headroom, and an 11.9 L drawer. For a long or tall cat, SC10 may be the better large-cat fit; for a cat needing a lower step, privacy, or a wider enclosed cabin, SC09 may be better.

“Big” has at least six meanings.
Exterior footprint, bed length, width, doorway, vertical headroom, entry height, and waste capacity answer different buyer questions. Naturally, product pages often hand consumers one litre number and retreat from the scene.
Exterior body
Determines whether the unit physically fits the room. SC10 is the longest current body; SC09 is wider, deeper, and slightly taller.
Usable floor or bed
Determines whether a cat can stand, dig, turn, and cover. SC10 has a manufacturer-stated 500 mm bed; equivalent internal floor dimensions are not published consistently for SC09.
Headroom
Open models have no ceiling. That matters for tall, upright-postured, or enclosure-averse cats even when their published litre number is lower.
Entry height
Lower is better for many petite, senior, arthritic, or short-legged cats. SC01 is lowest; SC09 is lower than SC10.
Waste drawer
Determines how much transferred waste can be stored, not how much room the cat has. SC10’s 11.9 L drawer is about 1.78 times SC09’s 6.7 L bin.
Volume label
An enclosed-cabin volume and an open litter-area volume are not the same measurement. Ranking them numerically without explaining the boundary is decorative arithmetic.

| Model | Exterior | Published space | Usable cat-space meaning | Entry | Waste bin |
|---|---|---|---|---|---|
| SC01 | 20.87 × 21.85 × 20.47 in | 56.7 L interior Manufacturer-stated enclosed drum volume. | Compact enclosed rotating drum; no current official floor-length or turning-diameter measurement was located. Fixed by the enclosed drum. | 4.8 in, the lowest current published entry. | 6 L |
| SC02 | 19.3 × 19.3 × 21.45 in on the current exact product page | 75 L interior Manufacturer-stated enclosed drum volume. | Larger opening and drum than SC01; official pages do not publish a directly comparable floor length or turning diameter. Fixed by the enclosed rotating drum. | 6.1 in on the current exact product page; other seller channels publish different entry figures. | 3.6 L on the current exact product page; other official variants have published 4 L. |
| SC03 | 23.6 × 17 × 7.8 in; seller listings sometimes swap axis labels while retaining the same measurements | Open tray; no comparable litre volume confirmed Open rake tray geometry cannot be compared honestly with enclosed-cabin litre claims. | Low, open tray with no overhead enclosure; practical length and width matter more than volume. Unlimited because the tray is open. | Approximately 7.5 in in the current research record. | Sealed waste bin; a stable current litre figure was not confirmed. |
| SC09 | 24.8 × 20 × 22.48 in | 106 L enclosed cabin Full enclosed volume, including air space inside the roofed shell. It is not directly comparable with SC10’s open-basin litre figure. | Wider and deeper enclosed body than SC10, with a roof and fixed doorway. Internal floor length and turning diameter are not published consistently. Fixed by the enclosed cabin roof. | 8 in on the current product page; the official comparison publishes 8.27 in. | 6.7 L |
| SC10 | 25.79 × 16.93 × 21.26 in | 72 L open litter area Open basin or litter-area volume. It excludes the unlimited air space above the bed and therefore cannot be compared directly with SC09’s enclosed 106 L cabin. | 19.7 in / 500 mm extended litter bed in the current official comparison, plus an open top and long overall chassis. Unlimited because there is no roof. | 9.48 in on the current product page, a higher step-over than SC09. | 11.9 L, about 1.78× the published SC09 bin volume. |
The size record for each model.
56.7 L interior
SC01
Smallest practical positioning in the current line, with the easiest step-in but the least convincing geometry for long-bodied cats.
Read the complete SC01 reviewWhere it is genuinely bigger or easier
- Lowest current published entry height.
- Compact positioning for tighter rooms.
- Mature owner evidence makes real fit limits easier to research.
Where the size claim breaks down
- Long or large cats may fit the weight range while still feeling cramped.
- The litre figure does not reveal usable turning room.
- Urination direction can matter more than body weight for leakage risk.
Large-cat fit: Not the first large-cat choice. It is better understood as the compact, low-entry model for smaller cats and constrained spaces.
Evidence boundary: Dimensions, capacity, entry, and weight range are manufacturer specifications. Cat-fit limits come from exact-model owner and editorial reports rather than an independent geometry test.
75 L interior
SC02
The line’s middle-size enclosed drum: more usable than SC01 for many cats, but clearly below SC09 and SC10 for maximum movement space.
Read the complete SC02 reviewWhere it is genuinely bigger or easier
- More room and published cat-weight headroom than SC01.
- Smaller exterior body than SC09 and SC10.
- Middle-size compromise for homes that cannot place the two largest models.
Where the size claim breaks down
- A 20 lb cat can still be too large in practice despite seller weight claims.
- The globe is heavier and more awkward to deep-clean than its exterior dimensions suggest.
- Official and seller-channel dimensions, entry, bin, and cat-range figures conflict.
Large-cat fit: A middle-size option, not the default large-cat recommendation. Long-bodied or approximately 20 lb cats should be measured against the real opening and interior rather than the weight claim.
Evidence boundary: Published measurements are seller specifications. Owner reports provide fit warnings but do not establish a universal maximum cat length or weight.
Open tray; no comparable litre volume confirmed
SC03
Open and low, but not automatically “large.” Its advantage is absence of a roof, not independently measured turning space.
Read the complete SC03 reviewWhere it is genuinely bigger or easier
- Open access for cats that reject globes or roofs.
- Low overall structure and no overhead restriction.
- Easier visual inspection of the litter surface and rake path.
Where the size claim breaks down
- Open sides increase scatter exposure.
- One long or tall cat reportedly avoided the tray despite large-cat marketing.
- The rake and grader create a different mechanical clearance problem than a drum.
Large-cat fit: Potentially useful for enclosure-averse cats, but not proven as the roomiest large-cat choice. Bed length, rake clearance, posture, and cat acceptance need direct verification.
Evidence boundary: Current official imagery and product material establish the open dual-rake design. Long-term owner and large-cat fit evidence remains small.
106 L enclosed cabin
SC09
Bigger as an enclosed cabin, not bigger in every useful dimension. SC09 wins width, depth, privacy, and lower entry; SC10 wins length, open headroom, and drawer capacity.
Read the complete SC09 reviewWhere it is genuinely bigger or easier
- Largest published enclosed-volume figure in the current line.
- Wider and deeper exterior body than SC10.
- Lower step-in than SC10 and better privacy or odor containment for cats that prefer a cabin.
Where the size claim breaks down
- The roof and doorway constrain tall or vertical-postured cats.
- A named 16 lb owner report disputes the comfort implied by the 30 lb seller claim.
- The 106 L number can overstate practical movement because it includes enclosed air volume.
- The waste bin is materially smaller than SC10’s drawer.
Large-cat fit: Strong for large cats that prefer an enclosed cabin, need a lower entry, and fit its doorway and turning geometry. It is not automatically better than SC10 for long or tall cats.
Evidence boundary: The 106 L, dimensions, entry, weight range, and 6.7 L bin are manufacturer claims. The fit complaint is one exact-model owner report and cannot establish typical fit.
72 L open litter area
SC10
SC10 is plausibly the more usable “big cat” machine for length, posture freedom, and multi-cat drawer capacity. SC09 remains the larger enclosed cabin. Neither single litre number settles the decision.
Read the complete SC10 reviewWhere it is genuinely bigger or easier
- Longest current chassis and the only current model with a published 500 mm extended bed.
- Unlimited vertical headroom for tall or upright-postured cats.
- Largest published waste drawer in the current line.
- Open visibility makes cat posture, litter level, and physical faults easier to inspect.
Where the size claim breaks down
- Narrower exterior body than SC09.
- Higher entry can be worse for petite, arthritic, or short-legged cats.
- No official maximum cat weight is stated on the current exact product page.
- The 500 mm bed and large-cat comfort claims remain manufacturer measurements until independently verified.
Large-cat fit: Often the stronger candidate for long, tall, or enclosure-averse cats because it is longer and has no roof. SC09 may still be better for cats needing a lower step, a wider enclosed stance, privacy, or stronger odor containment.
Evidence boundary: Dimensions, 72 L litter area, 500 mm bed, unlimited headroom, IPX5, noise, and drawer figures are manufacturer claims. The site’s 28-day household record validates observed operation and one jam mechanism, not an independent dimensional test.
Which MeoWant is best for a large cat?
The longer 500 mm bed and unlimited headroom are the strongest current geometry case. Confirm the higher step-over and keep the small external sample in mind.
The wider, deeper enclosed cabin and lower entry can be the better fit when doorway and turning space work for that cat.
SC09 has the lower step than SC10. SC01 has the lowest step but much less convincing room. A ramp may solve entry while doing nothing for internal turning space.
Body length, shoulder height, turning posture, digging style, and doorway comfort matter more than a seller maximum in pounds.
Size questions that actually change the purchase
Is SC10 bigger than SC09?
SC10 is longer and roofless, with a 500 mm bed and an 11.9 L drawer. SC09 has more enclosed volume and a wider, deeper, slightly taller shell. The answer depends on whether “bigger” means cabin volume, body length, standing room, entry, or waste storage.
Why is SC10 only listed as 72 L?
The official comparison says 72 L describes the open litter area, while SC09’s 106 L describes the full enclosed cabin. The numbers do not share the same boundary.
Is SC09 automatically best for a 20–30 lb cat?
No. The 30 lb range is a manufacturer claim, and one exact-model 16 lb owner report says the cat lacked comfortable covering room. Verify geometry and return cost.
Does open top always mean easier access?
No. Open top removes the roof, but entry height still matters. SC10’s current published step-over is 9.48 in, higher than SC09 and much higher than SC01.
