Both models use an open-top approach intended to give cats more visual and physical space than a front-entry globe. The M1 Plus generally makes more sense as a ready-to-use bundle; the M1 Lite Plus is the value choice when its lower listing price still saves money after adding only the accessories you need.

We checked Neakasa’s product pages and bundle comparison on September 9, 2026. Manufacturer bundles may differ from the Amazon listings linked here; confirm the exact listing before buying. This is independent desk research, not a hands-on litter-box test. Listings, bundles, sellers, and prices can change.
The meaningful differences
More complete starting kit
- Litter mat commonly included
- Extra starter waste bags
- Best when the bundle premium is modest
Buy only what you need
- Lower-cost entry when discounted
- Same open-top buying logic
- Add step, fence, or AirStep separately
Five checks before ordering
- Measure entry access. Weight limits do not replace a mobility check.
- Confirm litter compatibility. Use fast-clumping granular litter that the current manual accepts.
- Compare what is in the box. A cheaper listing can cost more after adding a mat, bags, or step.
- Verify seller and returns. Marketplace terms can differ from the manufacturer’s direct store.
- Keep the old box during transition. Let the cat investigate before enabling automatic cycles.
Which one should you buy?
Choose the M1 Plus when you want the more complete starting package and the included mat and additional waste bags are useful immediately. Choose the M1 Lite Plus when the current price difference is meaningful and you would rather add a ramp, fence, mat, or AirStep separately—if needed at all.
Before ordering, compare the final cart totals rather than the headline prices. Confirm the exact bundle contents, seller, delivery date, return terms, and litter requirements on the listing you are purchasing.
