Buying Guide: What to Look for in Neakasa M1 Accessories

Before you add any accessory to your cart, consider how it fits your cat’s behavior and your cleaning habits. Here are the key factors we evaluated for each product.

Compatibility and Fit

Not every accessory labeled “Neakasa M1” fits every version of the box. The M1, M1 Lite, and M1 Plus have slightly different entrance designs and waste drawer dimensions. Always check the product description. For example, the Neakasa Elevated Entrance Fence for M1 Lite is designed specifically for the Lite model, not the original M1. When in doubt, measure your unit’s opening and compare it to the listed specs. For broad compatibility, the CoveCozy litter bags fit both the M1 and the PetPivot AutoScooper 11.

Material and Durability

Accessories made from PP (polypropylene) or silicone are lightweight, easy to clean, and resist odors. PP is rigid and works well for entrance guards, while silicone offers flexibility for gap-sealing mats. Avoid items made from thin, brittle plastic, they crack after a few months. The Neakasa branded guards use non-toxic, odorless PP that holds up to daily cat traffic. For stain resistance, the YESORMLING silicone mat sticker adheres firmly and wipes clean.

Ease of Installation and Maintenance

You do not want to spend time assembling or removing complicated parts. The best accessories install in seconds, peel, stick, or snap on without tools. Drawstring waste bags simplify disposal and reduce contact with soiled litter. If you have multiple cats, consider accessories that are quick to clean: a quick rinse under water is ideal.

Effectiveness at Containing Mess

The whole point of an accessory is to reduce the litter scattered outside the box. Elevated guards and entrance fences add a physical barrier that keeps litter and urine inside, especially if your cat kicks or pees high. A ramp can also catch stray granules because cats walk up rather than jump in. For cats that tend to urinate near the edges, a silicone gap sticker seals the seam between the box and the floor, preventing leakage.

Final Thoughts

After reviewing each accessory, we recommend starting with the Neakasa Elevated Entrance Fence for M1 Lite if you own the Lite model, it directly addresses scattered litter and urine overshoot with a custom fit and sturdy build. For daily waste management, the CoveCozy 80 Count Litter Bags Compatible offer thick, drawstring liners that make disposal fast and clean, and they work with both the M1 and the PetPivot. Pairing these two will noticeably reduce your cleanup time.

Frequently Asked Questions

Do I need an entrance guard if my cat doesn’t kick litter?

Even if your cat is a gentle digger, an entrance guard adds a barrier that helps contain urine spray. Some male cats lift a leg when urinating, and a low guard can stop spray before it reaches the floor. If your cat never scatters, you may skip it, but the guard also prevents litter from being pushed out during entry and exit.

Can I use regular trash bags in the Neakasa M1 waste drawer?

You can, but custom waste drawer liners are sized to fit perfectly, reducing bunching and waste of bag material. The CoveCozy bags match the 27 × 13 inch drawer and include a drawstring closure for easy tying. Regular bags may need trimming or folding, and they do not always stay in place during removal.

Will a ramp work with the Neakasa M1 Plus?

The ramp we reviewed is a third-party accessory compatible with the Neakasa M1 open-top design. It should work with the M1 Plus as long as the dimensions allow placement at the entrance. Measure the height and width of your box entrance and compare it to the ramp’s listed size (about 15 × 10 inches). For cats with joint issues, a ramp provides a gentler incline than a step stool.

How often should I replace the silicone gap stickers?

The YESORMLING mat sticker is designed to last 3 to 6 months before needing replacement. Clean the sticker and the box surface monthly to maintain adhesion. If the sticker loses its grip or shows wear, swap it out to keep the seal tight.
