Our Full Review: Coziley G1

Set against the Zhmz and EazyPaws units, the Coziley G1 holds up better in daily use than its price tier suggests — especially in a small apartment with more than one cat.

Your Apartment Smells Like Nothing Lives There

The sealed waste compartment locks odors away fast, not just masks them. For a lot of owners, the constant candle-lighting near the litter corner simply stops being necessary.

Even a Shy Cat Walks Right In

The cleaning cycle runs so quietly that even an anxious cat rarely flinches during a cycle. The 30cm entry opening gives cats room to enter without hesitation, and the interior comfortably fits larger cats up to around 15 lbs.

Check on Every Cat Without Leaving the Couch

The app-based health monitoring lets you track usage patterns for every cat from your phone, which is genuinely useful for spotting when one of them is off. Setup takes under 20 minutes and the interface is straightforward. One small note: the app can take a few tries to connect on first pairing, so budget a few extra minutes there.

The Cleanup Ritual That Takes Less Time Than Brewing Coffee

Pulling the waste drawer takes seconds, and the included roll bags make disposal clean and simple. There is no scrubbing, no scooping, no lingering contact with waste at all.

This unit is best suited for multi-cat households in smaller living spaces where odor control and quiet operation are non-negotiable priorities.

Our Verdict
9.5/10
Best for: Multi-cat owners in apartments who hate daily scooping duties
Not ideal for: Cat owners whose cats exceed 18 lbs or 20 inches length
