Whisker Vent Odorless Litter Box Through Wall Venting System, 12-Feet Vent Hose

This is our second one. We ended up with our son's cat, bringing our total up to 3 cats in our household. One box just wasn't enough. However a friend of ours has 5 cats and a similar litter box, but it's significantly larger. They only need one box. I wish we had realized theirs was so much larger and perhaps we would have bought it just to make the cats more comfortable.

Wish this was still available..... Ok it is not mass manufactured, but it works and works well. Have had to for 5 years now. We have multiple cats and NO odor. I was just checking in today to see if I need a backup after 5 + years.

I ordered this directly from seller and used my own litter box which installation was easy and its true no more litter box smell and I would definitely recommend to anyone who owns a cat so why not 5 stars the noise. It doesn't bother my cats at all so if you won't ever hear it then don't worry about it but I feel I was a bit misled on this part and want everyone to understand it has a very annoying hum. Now it isn't super loud and it doesn't keep me up but I am very aware of the hum and I have a door to the litter box and I have the litter box inside a bench I had made to hide the litter box. So I went out and got a timer so it goes off every 4 hours for 30min. At first I did this as I was worried my cats wouldn't use the box. The noise doesn't bother my cats I've seen them both go in it. And I have 1 box for 2 cats and clean it every 2 days. Granted this is a big box and for years I've dealt with the smell and now it's completely gone. Even when I clean it out I don't smell it. Mine vents through the wall. So get one but get a timer unless you won't ever hear the thing and make sure your cats are ok with the noise. Someone posted a comment about the noise too which got me worried and said their cats wouldn't use it at all. They didn't do the timer. My only regret is not doing this sooner. It would be great if they could figure out a way to hook it up so it goes on 15min after the cat uses it. Now that would be a 5 star product but still 4 stars is great. Trust me cat owners the price is so worth it. I did completely change the litter and clean the box with bleach so I will have to post a follow up in 2 months when the box isn't so fresh. If its still odor free when I lift the lid to clean it I may just change my rating to a 5 star. I can get used to a hum (sort of) to never be bothered by litter box odor.
