Litter-Robot™ 4

I recently purchased the Whisker Litter-Robot™ 4 from Cat Evolution, and I couldn't be happier with my decision. As a cat owner of five, I was in search of a reliable automatic kitty litter machine, and this product has had a profoundly positive impact on our household.

The setup was a breeze! I was pleasantly surprised at how quickly our cats adapted to the new system. Our feline family ranges in age from 3 to 15 years, and they all took to it without any issues. We kept two traditional litter boxes available to help with the transition.

One of the most significant changes I've noticed is the elimination of unpleasant odors. Gone are the days of coming home from work to be greeted by the smell of kitty **** or pee. We used to go through 2 to 3 bags of kitty litter each week and relied on puppy pee pads for accidents.

Managing litter twice a day has become a thing of the past. The Litter-Robot saves so much time—my back is grateful for no longer having to stoop and scoop!

Cat Evolution provided excellent communication and prompt delivery, which made the entire purchasing experience smooth and hassle-free.

I honestly have zero cons to report! We're already saving up for a second machine because this product has exceeded our expectations. I took the time to write this review because other customer reviews significantly influenced my decision to choose this brand and company. I cannot recommend the Whisker Litter-Robot™ 4 enough for fellow cat owners looking for an efficient and reliable solution!

2 cats, 3 litter boxes. It’s always been the most irritating task as we all know, and there’s been no way around it for maximum cat health and happiness. Additionally, as I live on the second floor in a relatively small apartment, the cats 1) can’t go outside 2) the amount of floor space that 3 decently-sized litter boxes take up is ludicrous.

So, after reading multiple reviews, comparing multiple models, and waiting for 2 years to decide whether it was worth the pricey gamble, I finally went for it.

TLDR? LIFE IS GOOD.

First off, the communication and service from cat evolution was excellent. I don’t have any difficulties or technical issues but feel very reassured that if I do, they’ll help me sort it out.

Long explanation of my setup and usage, for those who are debating it:

1. It definitely is big - and because it has to be plugged in (duh, I know, but my apartment has very inconveniently located outlets) definitely grab a measuring stick and some painter’s tape so you can map out where you might want it. Even better, go to your local woolies or bottlo and grab a few cardboard boxes, because it’s more the height (volume) of it as far as the size goes that “feels” big. (It’s about…knee height on me?) That being said, it’s obviously still *significantly* less space consuming than 3 separate litter boxes, and 500% tidier, and 10000% less work.

2. Setup: Easy enough. Slightly perplexing when adding on the litter hopper initially - the Whisker app asks you whether you purchased them “together or separately” — but it doesn’t matter?? So ok…you have to disassemble the ‘hood’ and put on the litter hopper-compatible hood, and my single and only complaint about the machine re: quality is that slotting the hood onto the front piece isn’t as slick or perfect of a fit as I would expect. I was quite worried for awhile because the instructions and videos, while explaining well what to do, also bang on about how (understandably) it won’t work if they’re not clicked in properly, because the barrel wouldn’t rotate. However, when I finally got it as good as I could, it’s working fine - it’s really just that the quality of the plastic, if it were slightly thicker or a bit more rigid, would make that easier and better.

3. Introducing cats: Cat 1 is very gregarious and easygoing, Cat 2 is skittish and very wary (both rescues, but she was much more feral). So I focussed on Cat 1 first, so that she would see him using it and also to start getting smells in. I note the companies emphasize you shouldn’t “force” your cats in (obviously); but if you know your cats, I found there’s a way to get them in without traumatising them. At first I picked up Cat 1 and played with him, then just carried him to the robot entrance and squatted down with him on my lap, so that he could naturally step into it. First go he walked in, turned around, and I let him immediately walk out. We did this 2-3 times - never forced him in, and always let him immediately walk out. On the fourth go he had a little pee and I stopped worrying!

I did the same thing with Cat 2, who jumped out much faster. However, I noticed something that I was sure would be an obstacle - she’s quite a small cat, and the Robot entrance sits somewhat surprisingly high off the ground. She doesn’t like jumping; even getting on to the couch she doesn’t jump but claws her way up, so I felt this was going to be a big impediment. So I knocked together a little ramp out of scrap wood, tacked some carpet onto it to entice them further (they like scratching it), and continued once or twice a day to gently carry her to it, let her walk in (once the ramp was there) and walk out. A very long and anxious ($$$$ worries!) 4 days, she finally had a little pee after I placed her in it!

Then, over the next 3 days, as recommended, I continued to a) let the current litter boxes remain uncleaned, and then b) gradually remove them, one litter box at a time (but only after Cat 2 had had a successful pee).

We are now in week 2, and both cats are regularly using it; no other litter boxes remain, and we’ve had no accidents! Cat 2 walks delicately up her ramp and I’m very sure that was a big part of it.

4. I recently started using FitLitter, and *love* it, so figured I’d give it a try in the Robot (the cats love it too). On the US/UK website it does actually say you can use crystal-style litter but that it will likely require more regular cleaning of the filters, etc. So far, so good. I definitely think a clay/clumping litter would be better, because an unnecessary amount of ‘clean’ crystals get dumped into the garbage when the Robot cleans; but so far I just do a little extra sifting before I toss out the waste - sadly this will probably mean eventually I’ll switch back to clay (only sadly because FitLitter is a great company).

5. THE HOUSE IS SO CLEAN. THE HOUSE SMELLS OF…nothing. I am both incredibly relieved after the huge expense and equally happy! The ti...

We bought our Russian Blue kitten, Rasmus, one of the very first Litter Robots to be sold in Australia. That was almost 11 years ago now. Whilst this Open Air robot
is still working, we decided it was
time to upgrade to the new Litter Robot 4 for Rasmus's 11th birthday this July. What we love most is the
wide opening for our 6.8 kg boy. Plenty of room for him to turn
around inside. The other pros are the very quiet cycling; the ease of
operation; the Whiska app; and deep
litter drawer. After a week of use
we have detected no odour at all.
Rasmus transitioned from his old
robot to the new one without any fuss. So happy with this purchase.
Looking forward to trying the
Litter Hopper when it becomes available. Thank-you once again to
Mary and the team at Cat Evolution.
We know that you are always there for us should we ever need you.

We already have one of these,original one we purchased,prior to the newer model,had a problem with the sensors,so we upgraded to a new one

My cats love this and I have found it to be mostly reliable. Unexplained wi-fi issues have given me a headache. Finding an affordable litter that does not stick to the globe is my main challenge. Wish the litter hopper was more affordable.
