If you have a squeamish side, reusable cat diapers might not be for you. They do have to be rinsed before tossing them in the washer for best results. So, while you shouldn’t need to get your hands dirty, you are going to get a little more up close and personal with pee and poop than you would with disposable cat diapers.

Since there aren’t many cat-specific diapers out there, you may want to look into the human side of things.

Also, human diapers have a highly adjustable waistband that will help you get a snug and comfortable fit around your cat’s smaller waist.

If your cat doesn’t like the bulkiness of a diaper, sanitary pants may be more comfortable. They offer some protection without being restrictive. These sanitary pants from SELMAI also feature a drawstring waistband to help adjust the fit on your cat. 

Sanitary pants aren’t as absorbable as diapers, so don’t expect them to perform in the same way. They are more for the occasional or minor accidents. They also aren’t as adjustable as diapers, so measuring your cat before purchasing will help ensure that you get a more accurate size.

How to Get Your Cat to Wear a Diaper

A gray and light brown cat with black stripes is lying down on a table, wearing a diaper and one of his legs shaved due to an injury.

Believe it or not, most cats aren’t going to jump into a cat diaper willingly. They will more than likely take some convincing. Your best bet is to go about it slowly and in steps that they are comfortable with.

  • Step 1:  Ensure that you have the right size and type of diaper by measuring your cat. 
  • Step 2:  Let your cat sniff, play with, or get used to the diaper. Leave it out for them to mess around with (but not destroy!) until they are comfortable with it.
  • Step 3:  Try it on. Go slowly and make sure your cat isn’t distressed. Put the diaper on and leave it on for a few minutes if they’re accepting. Remove it immediately if they don’t like it. Repeat until your cat is comfortable with the process. Offer lots of praise and pets if they’re accepting.
  • Step 4:  Leave it on. Allow your cat to wear the diaper while on the move. Let them run, play, or eat as they would normally with lots of reassurance and praise.
  • Step 5:  Change the diaper often as needed to decrease the chance for leaks, smells, and making your kitty uncomfortable.

If you’ve stumbled upon this article by accident, you may be wondering just who needs diapers for their cat anyway? You may be surprised to learn that cats may need to wear a diaper for several reasons. This guide will teach you everything you’ll need to know about getting your cat set up with some diapers.

Why Do Cats Need to Wear Diapers?

Even though cats tend to be very meticulous and clean animals, there may be times that they may need a little help. A cat diaper can help keep them and your house clean and keep them out of solitary confinement. Here are some of the reasons why your cat may need a diaper:

  • Incontinence: Urinary and fecal incontinence in cats can occur for a variety of reasons. Old age, injuries, or congenital deformities can interfere with a cat’s ability to control their urine or bowel movements. Rather than keeping your kitty locked up in an easily cleaned room, cat diapers can help to keep them and your home clean.
  • Recovery:  If your kitty is recovering from an illness or surgery, they may be temporarily incontinent. This can be due to a decreased function of their legs or their urinary tract or digestive system. Whatever the case, cat diapers can help take care of them while they recover.
  • Spraying:  Urine marking or spraying is a normal, yet unwanted behavior. Spraying lets other cats know the boundaries of their territory and becomes more prominent during times of stress. We all know that cat urine packs a pungent smell that tends to linger and that is hard to get out of upholstery and rugs, so rather than cleaning up urine marking messes, you can prevent them using a cat diaper.
  • Cats in Heat:  If you have a female cat that isn’t spayed, their normal estrous cycle can cause a bit of a mess. Kitties in heat may drip blood or urinate excessively, both of which can be unwelcome in your home. 

How to Choose the Best Cat Diaper

Whether your kitty has some temporary or permanent issues that require a cat diaper, choosing the right one can still be a struggle. That’s why it’s important to know what options are out there for you and to understand your cat’s needs. Here are things to consider when choosing the perfect product for your cat.

Types of Cat Diapers

Cat diapers fall into two main categories: reusable and disposable. Reusable diapers are made from fabric that has an absorbent liner sewn in. These diapers can be rinsed, washed, and reused. They generally cost more per diaper but should cost you less in the long run since it is a one-time purchase. They will be more labor-intensive since they will require rinsing and washing in between each use. However, they are more eco-friendly since most disposable diapers aren’t biodegradable.

Disposable diapers are made to be thrown away once they are wet or dirty. They can’t be washed or reused. They are usually cheaper per diaper but will require multiple purchases throughout a cat’s lifetime or condition. They tend not to be biodegradable.

Cat diapers can also be classified based on use. Some diapers are thicker and more absorbent for heavy use, while sanitary pants are more like underwear, so they are thinner and more for light use.

There are always human diapers. Human diapers can work well for a cat if you get the right size, especially in a pinch. They don’t have a designated tail hole, so you will either have to cut one or put your cat’s tail out through the leg hole. Human diapers have the advantage in that they are easy to get and generally less expensive than cat diapers, but they may not fit as well.

Sizes of Cat Diapers

Cats don’t vary in size as widely as dogs do, but there will still be some variation in which diaper size to get. Most cat diapers will give you a waist circumference range for the best fit. Most cat diapers have Velcro or “magic tape” closures that help you adjust the fit even further so that your cat can’t slip out of it.

Comfort of Cat Diapers

With different fabrics and thicknesses, cat diapers are going to vary in their comfort levels. Some cats will not like the bulkiness that thick diapers have, while others may need that thickness for their absorptive capacity. Other cats might not like the noisiness of disposable materials and would prefer the softness of washable fabric diapers. This is all going to depend on your cat’s preference and the diapers’ ability to meet your needs.

Along with fabric type and bulkiness, the comfort of a cat’s diaper depends on the “extras.” Some diapers may try to use adhesive tape as a closure. As we all know, adhesives and cat fur don’t mix, so it’s best to steer clear of these diapers. Instead, look for diapers that use Velcro or non-adhesive tape for closures. Some sanitary pants use drawstrings, which allow for high adjustability without sticking to your cat’s fur.

Price and Availability

When your cat needs a diaper, they generally need it now! With this in mind, make sure to choose a type of cat diaper that you can easily get your hands on. If you go with reusables, make sure you have enough to cover your cat during laundry day and so that you won’t be washing diapers daily.

Also, make sure cat diapers are affordable. Some cats may require a diaper for the rest of their life. That can add up in some situations, so be sure you can financially keep your cat in diapers for as long as they need them.

How to Determine the Best Size of Cat Diaper

Most pet diapers on the market are geared towards dogs. While this isn’t a deal-breaker for cats, it may cause some issues with getting the perfect fit. To choose a diaper that will properly fit your cat, you will have to take some measurements.

The most common measurement for cat diapers is their waist circumference. This can be found by measuring the thinnest part of the waist. If you don’t have a flexible measuring tape, use a piece of string instead to go around the narrowest part of the waist and then measure the string with a ruler or measuring tape. 

Other diapers may give you a length measurement. This can be found by measuring from the narrowest part of the waist to the base of the tail. This length measurement will help ensure that a diaper isn’t too baggy. Some diapers may also give you a weight range to choose from. Get an accurate weight on your cat using a scale.

Final Thoughts

Instead of relegating your cat to a life of confinement in the bathroom, give them back their freedom by using a cat diaper. Whether their situation is temporary or long-term, cat diapers can help keep your cat and home clean and sanitary.
