Our Top Cat Diaper Picks

Why Does My Cat Pee Outside The Litter Tray?

Generally speaking, there are four broad reasons why your cat may be peeing outside their litter tray. These reasons are that they may be incontinent, maybe be ill or recovering from illness, they may be spraying or on heat, or they may have been born with a birth defect.


An incontinent cat will leave trails of urine in different areas, exhibit constantly wet fur between the legs, and probably be licking its rear end more than usual. They will also probably smell of ammonia.

Incontinence can be caused by a variety of issues that usually relate to nerve damage or bladder sphincter weakness. Your cat may have had a fall and damaged its back resulting in incontinence issues. Age-related muscle weakness can cause bladder weakness, or muscle weaknesses resulting from overuse issues caused by conditions such as kidney problems, diabetes, or urinary tract infections. Maybe your cat has dementia and simply forgets or is confused as to what to do. Cat nappies can help in these situations.


Spraying cats are marking territory. This is a natural activity. Usually, cats will spray outdoors but if your cat sprays indoors this can be a problem. Often when a cat sprays indoors it can be related to stress issues – they can feel the need to assert their territory if they feel vulnerable. A diaper may be a solution until the spraying activity can be reduced.

Female cats that are not neutered will come onto heat. In these situations, it is normal for them to leave spots of blood, spray marks and urinate excessively to demonstrate estrus. A diaper can be effective at collecting this blood and urine and reduce the damage from spraying when they are on heat.

Illness/surgery recovery

Maybe your cat has a short-term illness like kidney stones that increases difficult urination or is recovering from surgery that has made mobility difficult for a short time and reduced the ability to make the litter box. In these situations, a diaper can help when kitty gets caught short.

Birth defects

If your cat has a naturally occurring defect that can’t be remedied by surgery a diaper may be the best option when they are kept indoors.

What types of diapers are available for cats?

Now we can see why you might consider a diaper for your cat it is time to look at the possible options available on the market so you can make an informed decision on which type of diaper might best suit your cat’s needs.


As the name suggests these are a one-use diapers. Typically utilizing an absorbent pad comes with fixing tapes and elasticated openings. Just bin then after use and you are done. Ideal for cats suffering short-term from incontinence issues like those recovering from surgery or other mobility issues.


A more environmentally friendly solution for those cats with longer-term issues. These cloth diapers are usually machine washable, feature pockets that can take an absorbing liner, and are usually either stud pants or have velcro fittings. If kitty has dementia or a case of permanent incontinence these could be the diaper for you.

cat pants

These are essentially a set of pants with elasticated leg, belly, and tail openings that can be used to hold an absorbent pad or liner in the correct position on your cat. Usually washable and available in a wide variety of stylish designs.

human baby diapers

If all else fails extra small human baby diapers might be the cheapest option for your cat. Obviously, they are not ideal as you will have to cut a tail opening but they are widely available and come in a whole range of options and price levels.

How To Choose?


Most of the pet diapers on the market are marketed to dog owners. Not many diaper options are purely marketed as cat diapers. Most dog diapers come in a range of sizes to suit large dogs down to chihuahuas. As a cat owner, you are going to have to look mainly at dog diapers but aim for the extra small and small sizes to suit a cat. To work out which size is most applicable you will need to measure your cat around the waist just in front of the rear legs. Most extra small options start at 4-inch diameter waist measurements.

washable or disposable

Is it worth getting washable cat diapers if your cat has a short-term issue? Disposables are cheaper but you have to keep buying them again and again. Go washable if kitty has long-term problems.

tail opening

Check for a tail opening or you are going to have to make your own! Some brands such as barkers actually make cat diapers without a tail opening for those cats that have had their tails docked or whose tails have not developed from birth.

comfort factors

Is the diaper going to be comfortable? Is it so bulky that movement might be restricted? Is it like to interfere to a degree that your cat might spend most of its time trying to remove the diaper? Would cat pants be the ideal solution as they are difficult for kitty to remove but then they are difficult to check regularly? These are some factors you will have to consider when you are buying diapers for your cat.

Best Cat Diapers Available

We have checked out the market to find the best cat diapers available that might be suitable for your cat. We have found a selection of disposable and reusable diapers that should be suitable. Don’t be put off if some of these diapers are marketed toward dogs. The small and extra small female dog diapers often make a good option for use with cats…


Pet Magasin Reusable Pet Diapers

Pet Magasin diapers are one of the most popular options available on the market. Don’t be fooled into thinking these are just for dogs….the extra small and small size options are ideal for average-sized cats and larger cats!

These are machine and hand-washable reusable diapers. They feature a waterproof outer lining and an absorbent inner lining – they can be used without absorbing pads but most owners suggest using absorbing pads for best use.

Comfortable to use, many owners find their pet is happy to use these diapers and many suggest their pet doesn’t try to remove them and they don’t become a point of focus.

The diaper is fitted by wrapping around the waist and closing with thick velcro straps. Features a tail opening for comfort. Each pack comes with a set of three so you can easily rotate.

These are a great option for an incontinent cat or an elderly cat with longer-term health issues.


  • Reusable
  • Waterproof outer, absorbent inner
  • Comfortable

  • Machine wash
  • Price


  • Not purpose-made for cats
  • Getting the right size can be critical to them staying on.

PetParents Washable Premium

These are very similar to the Pet Magasin option but are more suitable for smaller cats as the extra small version can be used on cats with a four-inch diameter waist. They supply other sizes so even if your cat is larger they will offer a suitable alternative.

Each pack features three diapers for the price and comes in three different, conservative, colors – black, grey, or rust-brown or alternatively a three-pack available in black.

These diapers feature a tail opening and wrap around the waist and fit with velcro tabs. The diaper can be machine washed or hand washed and features an absorbent pad that has a waterproof outer lining to prevent leakage.

Leg and tail openings are gently elasticated to help prevent leakage and to ensure a good fit.

  • Lots of good user reviews


  • Some users experience leaks

These are an easy to fit machine washable cat diaper that features a triple layer system. They have a poly-cotton outer, soft inner lining, and waterproof layer between inner and outer for leak-proof security.

Vets best Comfort Fit Disposable Diapers

Vet’s best comfort diapers come in four different sizes. The size we are interested in is the extra small option. This is suitable for most cats (but check the measurements – these are suitable for cats with a waist measurement of 12.5 to 16.5 inches).

These are disposable diapers and feature a wetness indicator so you can tell when to change, a tail hole ready positioned for easy fitting, and fur-friendly attachment tags for convenient fitting. They feature a super absorbent core and elasticated opening to prevent leaks.

Each pack comes with 12 diapers and a pack could be considered to be a medium price compared to other options.

The bad news is that reviews are very hit and miss. Quality issues, sizing issues, and price fluctuations mean these diapers appear to attract a number of negative reviews that can’t be ignored. In a slim market with few options, these are probably amongst the options to avoid…..


  • Elasticated openings to reduce leaks
  • Wetness indicator to indicate time to change


  • Quality problems
  • Sizing issues
  • Prices change frequently
  • Poor reviews compared to other brands

Paw Inspired Ultra Protection Disposable Diapers – 32 pack

These are the only other disposable diaper on our list and it is fair to say they do better than the Vets best discussed above! Again, these are marketed to dog owners but the extra small size bracket for toy dogs should be suitable for most grown cats.

These are a fairly normal absorbent diaper – they have a tail hole, super-absorbent gel pad, elasticated opening, and easy fit tabs – all pretty standard. You get a good pack size for the price. The difference with these is all in the user reviews.

These diapers score really well. There simply aren’t many/any negatives doing the rounds on these and there are hundreds of reviews so they are doing something right. Here is what it is – these are super absorbent, no leakage and they stay on good – even when cat owners review! Sounds to me like these do what they say on the tin and people are happy with the result. If a disposable is required this should be your first stop.


  • Elasticated openings
  • Easy fit tabs
  • Absorbent disposable diaper
  • Good value
  • Positive reviews from users


  • Not specific for cats so check sizes before buying

Our Favourite

In the machine-washable/reusable category, it really is a close-run thing. There are a number of options available all of which perform well. Spoilt for choice – but when push comes to shove we would opt for the Barkertime Cat Diapers because they are genuinely designed for cats and owners love them. Oh, and you get a funky range of designs and colors which kinda floats my boat!

If disposables are your go-to option then really you got one serious option and that is the Paw Inspired option. Great reviews mean you should have trouble-free use out of this option. Other pet disposables simply have too many inconsistencies and issues. If disposables are your favored option it might be worth buying baby diapers and altering to suit – that way you might save a bit of cash and still get a decent result!
