    About Modkat Flip Type-F liners

    Type F liners are the official replacement liners designed specifically for the Modkat Flip™ litter box. Integrated TabFit™ hanging tabs connect directly to the Flip’s lid pillars for a secure, custom fit.

    Third-party liners are not designed for the current Flip’s patented TabFit™ attachment system. Official Type F liners are designed around the Flip’s dimensions, attachment points, and full-height fit, attaching directly to the box as an integrated system.

    Integrated TabFit™ tabs hang directly from the Flip’s built-in lid pillars. No hooks, clips, or separate attachments required.

    No. The Flip can be used without a liner. Type F liners make cleanup easier while providing full-height coverage inside the box.

    The integrated tabs go on and off quickly, hold the liner securely in place, and eliminate separate hooks. The taller design provides more coverage, while the front pull tab locks the liner against the front of the box to help keep litter and mess from getting between the liner and the box.

    Type F liners are reusable. With normal use and care, we recommend replacing them about every three months, or sooner if they show wear or damage.

    No. Type F liners are designed specifically for the Modkat Flip. Their shape, height, and TabFit™ attachment points are made to fit the Flip.


    Reusable, washable liners designed for litter boxes. Customers praised the "durable" material and built-in tabs that replace clips. Many said liners "last a long time" (3-6 months). Some noted seams trap waste making cleaning difficult, and wish for non-stick material. A few mentioned white tabs are visible on black boxes and eyelets can rust when washed.

    Does what you think, and does it well.

    I didn't expect for the liners to arrive only wrapped in a shipping bag, but hey they arrived in one piece and it's definitely better than a giant box for them. Not much more to say than that! They did a good job of keeping the actual box clean, though my little lady still managed to get some underneath somehow. She does enjoy the box, especially with the fresh liner!

    Peaty loves it!

    He jumped right inside.

    As for me, I really wanted an easy to clean, and handsome litter box, because in my tiny apartment it sits next to the toilet!

    Love Modkat

    Modkat pans and liners are a game changer. Without these as an option, we would have had to live with urine stains and might not have been able to keep our amazing high-peeing kitty. High quality products that are a good investment for kitties and their people.

    Love!

    I love these.They're super tough and sturdy. I always keep extra in case Ari gets over exuberant when kicking litter. He's been known to scratch through the liner which is *really* hard to do. Ari is 15 pounds of muscle though and has head butted furniture out of his way, so...

    The Poo Condo

    My kitty LOVES her Flip Top litter box. Had it a few years now and it’s just as nice as the day I bought it.
    Ran out of replacement liners during quarantine. Found it less expensive going directly to Modkat than Amazon, and better customer service as well.
    And liners actually last longer than expected, so don’t ever change them!
    And yes, we do call it the Poo Condo.
    Thank you Modkat!!

    Nice

    I haven’t used the new ones as the originals are still good. If the new ones are as good as the originals then I like them. The liners are a big help, hard to dry after washing but not that difficult just takes some work. I may use the replacements so I can wash and dry the old ones, cycle them through, just thinking about it. I like Modkat products but very expensive.

    Excellent products

    Just love everything. I bought 3 and loved them so much. I bought a 4th one. Plus bought the mates and the spay. I am happy and the cats are happy. Thank you so much.

    Modkat Flip Liners

    I love these liners! They are super durable and nothing sticks to them. These litter boxes and liners have made my life so much easier. I am an owner of 6 cats and these liners are a life safer if you own "high pee-ers". I highly recommend.

    Gives us a clean look

    I really liked our 1st two so I purchased a 2-pack in white. Clean look. We now have 5! With as much activity as we have I’ll probably try eliminating the liner on one to see how it goes. Along with switching to a gentler litter I think the liner might last longer. The box design itself is great. We’re very happy

    The BEST litter box

    I have owned cats for 40 + years, I have finally found my dream litter box. It is practical, the design is perfect , the concept is amazing. The charcoal pouch eliminates all odors. The sides and back are enclosed so no litter gets on the floor. The liners are a genius idea, it says you can wash them every few months and re-use , they are cheap enough that I am just going to re-purchase every three months so it is like a brand new litter box at that time because the outer box doesn’t get dirty at all ! I recommend this product to any cat person out there ! You will NOT be disappointed!

    Flip Liners - Type F (3-Pack)

    Love these! And they shipped so fast. My kitty loves his modcat box and liner so much that when I freshly clean it and put new litter in each week he goes in there and digs around in the litter (not going potty, just playing!) and then sits on top of the piles he makes, looking pleased as punch. Thanks ModCat!

    Always good quality

    Liners are well made and stand up against well to cats’ claws. I will put in a new one next weekend. I use one liner for 3-4 months before I put in a new one, saves money. A little pricey but using one liner more than one month helps make up for the cost.

    New design

    I am withholding judgment on the new design of the F liners until I see how they work out. I was taken aback when first taking them out of the packaging. Gone were the sturdy metal grommets that previously held the liner in place, replaced by the flimsiest of plastic with no instructions how the liner was to be secured. I figured it out but am disappointed. One of my cats is a very aggressive coverer of his feces and I’m afraid one or more corners of the liner is going to be pulled off to collapse the whole liner into the litter box, something he could not do with the hooks and metal grommets. Did you even ask your customers if they wanted this??

    Tabs better than the clips

    I like the built in tabs to secure the liners rather than the clips

    Really love this box system

    Really love this box system. We have one cat that sprays high and this is the perfect system for him. The only gripe that I have with the liner (awesome redesign though because the clips were not great) is that it is not seamless. I don't know if the liner can be just one giant piece or somehow not have seams because litter and poop get caught inside and it's a terrible time cleaning. I usually wash the liners once a week and replace them every 3 months and they hold up great but the seams...Will still be getting more boxes because this is the best litter box I have had in a long time and I have 5 cats.

    Too much for a cat that is not a problem. If you have a cat that sprays this might be good

    Hi Christina, thank you for sharing your experience. If you'd like, all of our boxes can be used without a liner as well if you'd like!

    Best litter box system

    I finally found a litter box that works with both of my cats -- the female who demands a pristine box and the male who pees standing up. Truly a game-changer.
