Adaptive Self-Cleaning Algorithm. The HKM-392147 employs a weight-sensitive platform combined with infrared motion detection. After your cat exits, a countdown initiates — typically 90 seconds — ensuring complete safety before the automatic sifting cycle begins. Waste is separated into a sealed lower compartment, reducing odor leakage by up to 85% compared to open trays.

Whisper-Quiet Operation. The brushless motor operates at less than 45 dB during cleaning, quieter than a household conversation. This low-noise design helps timid or anxious cats adapt faster. The round drum rotates smoothly on precision bearings, eliminating sudden jerks that might startle your pet.

Multi-Cat & Large Breed Ready. With a usable interior floor area of approximately 460 in² (0.30 m²), even Maine Coons or Ragdolls weighing up to 22 lb find comfortable positioning. The weight sensor automatically distinguishes between different cats (when weights differ by >1.1 lb / 0.5 kg), logging individual usage in the companion app.

App Ecosystem & Smart Home Integration. Connect via 2.4G or 5G WiFi networks. The HKM Home app (iOS & Android) displays real-time litter box status, 7-day usage history, and waste drawer fullness. Push notifications alert you when the waste container reaches 80% capacity. Compatible with voice assistants for basic status checks.

Designed Around Feline Behavior

The distinctive round architecture isn't just aesthetic — it mimics the enclosed dens cats instinctively seek. The entryway sits at a comfortable 7.9 in (20 cm) height, easy for seniors or kittens above 3.3 lb. Inside, the texture of the PP surface provides secure footing without abrasive ridges that might deter sensitive paws. The carbon-infused filter module snaps magnetically into the rear ventilation port, replaceable every 30 days for peak performance.

Easy Deep Cleaning. The entire globe separates from the base with a quarter-turn release. All plastic components are rinseable with mild soap and water. The waste drawer includes a smooth, non-stick coating that resists clumping litter adhesion, reducing scraping during monthly deep cleans.

Frequently Asked Questions
What litter types are recommended? +
Clumping clay or silica gel litter works best. The sifting grate is optimized for particles between 0.08–0.2 in (2–5 mm). Avoid non-clumping, pine, or crystal litters with oversized granules, as they may not sift efficiently.
How often must the waste drawer be emptied? +
For one average-sized cat, approximately every 5–7 days. The app provides percentage-based alerts. Drawer capacity is 3.3 gal (12.5 L), accommodating multiple days of waste for multi-cat households.
Is it safe for kittens under 3.3 lb? +
The weight sensor requires a minimum of 3.3 lb (1.5 kg) to reliably detect presence. For kittens below this threshold, we recommend manual mode until they reach the safe weight.
Does it work during a WiFi outage? +
Yes. The onboard button panel retains full cleaning functionality offline. Scheduled cycles stored in local memory continue to run. App features resume automatically when connectivity is restored.

Tough Dog Balls. Bright Orange/holes for treats
Color: B) 3" 2-Pack (Bacon)
I used to buy Starmark. But their balls got smaller and tore more easily. The color was green. I couldn’t find it when it was dropped in the grass!! Soooooo, I took a chance on this cuz it had holes in it and was bright orange. It is not scented at all or its bacon scent faded. The ball is for strong chewers. I’m a petsitter and I needed tough balls for my clients dog. Shipped quickly. Good price. Exactly as described

Flavored Dog Rubber Balls
Color: H) 2.5" 3-Pack (Beef), Color: H) 2.5" 3-Pack (Beef)
My dog absolutely loves these balls, I have a few more I had already bought, but she has an addiction to them so I had to buy more. I am able to squeeze these really easily so when she does pick them up after I’ve thrown them they’re very easy for her to pick up. They have a good thickness to them so it’s not too flimsy. It’s pretty tough and they bounce pretty high which I like and so does she know she is an aggressive chewer, but I haven’t had an issue yet with her chewing right through these, which is why I like them and we both love the fact that it smells like beef I could practically smell them through the bag, but I have a really high pitched sense of smell, and I knew she was going to love them. Not to mention you can’t beat the price.

Love These Balls
Color: H) 2.5" 3-Pack (Beef), Color: H) 2.5" 3-Pack (Beef)
These are great balls. My Border Collie can destroy a tennis ball in a couple of hours and the Kong brand ball is heavier than I like to play with in the house. These balls hold up to her biting and chewing but are lite weight and softer for bouncing off the walls.

Seems durable - but the scent is not the best
Color: B) 3" 2-Pack (Bacon)
I don't know if I'd call the scent of this "bacon," more like rubber with a hint of bacon. It's very strong. I gave my dog one of the balls & put one in a cabinet where I keep his treats & a few other unrelated odds & ends. I now hold my breath when I open that cabinet b/c good lord, the smell. I'm tempted to just give that one to the dog too, just because it'll air out eventually & then everything else in that cabinet won't smell bad. My dog feels so-so about it. He'll briefly chase after it & chew on it, but loses interest in it pretty fast. My rather hyperactive cat also plays with it from time to time, as he seems to have more interest in most dog toys than the dog these days, so there's that. (Then again, he thinks a wide variety of random items around the house are loads of fun to toss about, so it's possible his opinion is to be taken with a grain of salt. Between the brief periods of one of these balls being chewed on & clawed at, it's stayed completely intact. I think if you have a dog who simply likes to play fetch or chew on rubber balls in general, this one would stand up to the task. But if you're expecting it to be greeted with the enthusiasm as a bacon grease covered ball might be - I'd adjust your expectations.
