Litter Change Tip

Pro Tip, make sure you are using suitable clay clumping litter in the manual litter system BEFORE introducing the Robot, as familiar litter will help your cats recognise the Litter-Robot™ is a new litter box, just a different shape, and will make the transition faster and easier for all.

Worth it!

Absolutely love this product! I've had it up and running for 1 week and even though it is early days, I'm very pleased I made the purchase. I have chronic fatigue from MS and this has made my life so much easier.

Heaven Sent

Still early days but so far so good.
We have 4 cats and whilst 2 are still watching, the other 2 have adopted the new technology easily.
The LR4 arrived very quickly (thank you) and the cats enjoyed playing in the huge box after setup.
We have stopped wasting kitty litter by needing to clean out 5 litter boxes regularly because of the urine/ammonia smell and scooping twice a day and then throwing out more than necessary just because it gets that stale smell.
The smells are now contained in the removal tray and the kitty litter left in the bowl appears clean and fresh all the time as the waste doesn't sit there for hours contaminating the entire box.
Excellent!! Talk to me in 6 months...

Julie Anne Whitehead

I love the new look and at the moment it is working well. I have MS and it is a game changer for me not having to deal with the litter boxes every day.

A few bugs but still amazing!

Firstly I should credit Cat Evolution for such a quick transaction and shipment, It was at my doorstep within 72 hours of placing the order! The packaging box is huge... not too heavy to handle, so be prepared to dispose of it when empty. The LR4 is the first automatic litter box I have owned... and it has changed my life! No longer do I get those litter box smells a few days after changing over the litter or having to scoop multiple times during the day. I have a 3 month old kitten who made the transition to the LR4 in 24 hours, and I removed her litter tray out of the room after 3 days. The guard at the front of the opening has decreased the tracking of kitty litter, and the sensors have been working overtime detecting my kitten who is super curious every-time it cycles and want to inspect the machine a few time causing it to pause. I had a few issues with the weight sensor, where I needed to reset it, also the app has a few bugs including the data display not displaying all the time, and resetting my preferences on the machines settings which included the panel lock feature, which caused an issue when my cat jumped on the hood and walked over all the buttons. The rotation of the globe when cycling is super quiet, I can't hear it when I leave the room (which is the laundry) and barely hear the motor, just the movement of the litter. I also use Worlds Best Cat litter (Green Bag) and can't smell a thing, even when the drawer is 50% full over 6 days. The fact that it keeps the waste sealed underneath the globe means this also helps keep my dog who is attracted to the kitty litter and its deposits out when I am not looking.

So... is it worth the money? I think it is a luxury item for sure, but if you work away from home and unable to scoop up traditional litter boxes throughout the day and you want to avoid the smell and mess at all costs, then yes you will love the RL4 and so will your cat!

Cat evolution have been excellent but the whisker app is hot garbage

Im happy i bought this because my one fussy cat is using it, however if i were to compare this to the petkit purax which i also have, id say its not worth the price hike.

Ill start by saying cat evolution have been excellent. The updates and reassurance and detail in their communication is beyond what one would expect from customer service at any level. Everything was like clockwork and they deserve every bit of praise.

The robot when first unpacked feels a little cheap. The hood over the globe is flimsy and doesn’t sit flush with the body of the unit. This is my only beef with the physical unit. The good parts is that the wide opening has helped my one floor-pooper start using the box again. The globe is huge and so is the waste chamber. Theres not much odour at all so im pretty happy in that regard.

The app is the biggest let down. It rarely loads any data at all. I need to repeatedly crash it and re open and wait upwards of a minute to see if i can get any info. Sometimes it will detect a cat, then half an hour later it will do a cycle and it wont tell me until many hours later which cat actually used the box. This is problematic if you need to monitor health/urinary/gastro symptoms. It doesn’t share any data about how long the cat toileted for and doesn’t tell you when the cat used it at the time (it tells you when a cycle completes but not when the cat is in the box).

Ive also had troubles with the app not manually cycling when i press the manual cycle button if the bot is already counting down, however you can manually cycle it by pressing the button.

These are all kinda minor inconveniences but not if you’re paying $1000 more than the competitor products who don't have these issues.

Tldr, if it weren’t for my cat who prefers this over the Petkit, i would have probably not held on to it. I hope whisker fix their app though because it would significantly improve the experience and value perception of this product.

Thanks again catevolution team ❤️ youre legends!

Thank you for your indepth review, as we value feedback and will be passing the information onto Whisker, who are generally quite responsive which is helpful.
The APP has had quite a few revisions, and has not been as stable as a result.
I believe it is largely due to updates and improvements, plus feeder and now introduction of the hopper (see USA as not released overseas yet) all of which can cause instability and unexpected issues.
​We are aware that firmware, and software updates are challenging, as there are multitudes of devices, modems and apps that are interfacing now.
​As a note on the hood, I am hoping it will be improved as it does feel light weight compared to the rest of the LR4.
