Will a Stray Cat Use a Litter Box? The Answer May Surprise You.


Stray cats often appear healthy and self-sufficient, so you may wonder if they even need human provisions like a litter box. However, providing stray cats with a clean, accessible litter area can greatly benefit both the cats and the surrounding environment. According to a study in Japan, stray cats exclusively used outdoor litter boxes within weeks of them being introduced and stopped inappropriate elimination in yards or public areas (Alley Cat Allies). This highlights how even stray cats that are not accustomed to litter boxes will learn to use them when given the opportunity.

Reasons Stray Cats May Avoid Litter Boxes

Stray cats that have lived outdoors may not be accustomed to using litter boxes regularly. According to Quora, “Stray cats, although they may not have been exposed to litter trays in the past, often quickly adapt to using them due to [instinct].”1 Lack of familiarity and previous experience with litter boxes is a primary reason a stray cat may avoid using one at first.

Since stray cats are used to going to the bathroom wherever they want outside, being restricted to a litter box indoors can take some adjustment. With patience and positive reinforcement using treats and praise, stray cats can learn to use a litter box successfully.

Getting a Stray Cat Comfortable with a Litter Box

Stray cats that are new to living indoors may need some help getting acclimated to using a litter box. Here are some tips:

Put the litter box in a quiet, low-traffic area of your home to help the cat feel comfortable using it without disturbances. Sheltered areas like a laundry room or bathroom often work well. According to Longmonth Humane Society, confinement or close supervision can be helpful when beginning litter box training with a stray cat. Keeping them in a small room with food, water, bedding, toys, and the litter box allows you to monitor their bathroom habits closely.

Use an unscented, lightweight litter without a lot of dust. Strway cats are used to going to the bathroom outside in dirt or sand. A simple clay or clumping litter without added fragrances will feel more familiar. According to Pretty Litter, strong scents from heaviliy scented litters may put off a stray cat unfamiliar with indoor litter.

Give the cat privacy when using the litter box. Shelter the box location to make the stray cat feel more secure. Cats like to be able to enter and exit the litter box freely and without an audience. Allow them do their business without interruption.

Litter Box Location and Type

When providing a litter box for a stray cat, the location and type of box are key factors that can determine if the cat will use it. Stray cats often prefer discreet locations that provide privacy while allowing them to feel safe. Multiple litter box stations around your property give stray cats options and account for territorial boundaries between cats. Covered litter boxes offer privacy, while uncovered boxes allow for better ventilation and may feel less confining.

Ideally, litter boxes for stray cats should be placed in quiet, concealed areas of your yard that are easily accessible to the cats ([1]). Good spots are tucked beside porches or under bushes. The boxes should be kept away from their food and water to avoid contamination. If you notice spots where cats are already eliminating, put boxes in those areas initially to encourage proper litter box use.

Having multiple litter box stations, rather than just one ([2]), helps accommodate different cats’ territories and makes access easier. While uncovered boxes allow cats to watch for threats, covered boxes provide more privacy and protection from the elements. High-sided litter boxes also help keep litter contained. Offering both types allows cats options to suit different preferences.

The key is observing stray cats’ behavior to determine ideal locations and box types. Trying different setups and making adjustments based on actual use is often needed. With patience, you can discover which litter box solutions work best for your strays.

Litter Preferences

When training a stray cat to use a litter box, it’s important to pay attention to their litter preferences. Stray cats that have lived outdoors are often accustomed to going to the bathroom in sand or soil. Therefore, they may prefer a finer, sand-like texture in litter as opposed to larger pellets or crystals (source). Litter types like World’s Best Cat Litter or Dr. Elsey’s Ultra Cat Litter tend to have a soft, sandy texture that mimics what stray cats are used to outdoors.

In terms of scent, most experts recommend using unscented litter for strays (source). Scented litters can be off-putting or overwhelming for cats new to indoor litter boxes. An unscented, sand-like litter is the best way to help a stray cat feel comfortable using the litter box. You can also try a natural litter attractant like Dr. Elsey’s Cat Attract litter if the stray cat is hesitant about using the box at first.

Cleaning the Litter Box

Keeping the litter box clean is essential for encouraging a stray cat to use it. A dirty litter box can deter even the most well-trained cat from doing their business. Experts recommend scooping solid waste from the litter box daily. The entire box should be emptied, washed, and refilled with fresh litter at least once per week.

For a single cat using one litter box, most vets advise fully changing the litter every 1-2 weeks. With multiple cats, the litter may need to be changed more frequently. The litter box should always be kept free of solid clumps and moist, sticky litter. Signs it’s time for a full change include a strong ammonia odor or visible dirtiness.

Cats have a strong sense of smell and will avoid a dirty box. One Reddit user does a deep clean with hot water and vinegar every 2-3 months. This helps remove odors and bacteria that can linger even after scooping. For stray cats new to the litter box, err on the side of cleaning it more often as they adjust.

With good litter hygiene habits, most cats will consistently use their box. The key is preventing the buildup of waste that can repel cats. By scooping daily and changing the litter completely every 1-2 weeks, stray cats can develop a habit of using their fresh, clean litter box.

Transitioning an Outdoor Cat

Transitioning an outdoor or stray cat to live indoors full-time can take patience and effort. Outdoor cats are often not accustomed to being confined indoors and may try to dart outside when given the chance. Here are some tips to help the transition go smoothly:

Start by keeping the cat contained in a small room with food, water, litter box, toys, and places to sleep and hide. This “sanctuary room” helps the cat adjust to indoor living before introducing the rest of the house.[1]

Make sure windows and doors are kept closed so the cat cannot escape. You may need to install child locks or other barriers.

Provide plenty of vertical space with cat trees, shelves, and wall-mounted perches. Cats like to climb and perch up high.[2]

Increase exercise and play time with wand toys, laser pointers, and interactive feeders. A bored cat may try to go outside seeking stimulation.

Use calming pheromone diffusers and treats to ease anxiety. New environments can be stressful.

Gradually expand the cat’s access to more areas of the home once settled in the sanctuary room.

Be patient! The transition can take weeks or months. With time, the outdoors will become less appealing to an indoor cat.

When to Seek Help

If you notice your stray cat struggling to use the litter box, it’s important to seek veterinary help. There are several medical conditions that can cause litter box problems in cats.

One of the most common is a urinary tract infection (UTI). UTIs cause pain and discomfort when urinating, which can lead cats to avoid the litter box. Other signs of a potential UTI include frequent trips to the litter box, crying out when urinating, and blood in the urine.

Kidney disease is another potential cause of litter box issues, as it leads to increased thirst and urination. Advanced kidney disease can also cause incontinence. Additional signs include increased water consumption, weight loss, poor coat condition, and foul-smelling breath.

Cats with arthritis or other mobility issues may begin missing the litter box due to pain or stiffness. You may notice them hesitating to jump in and out of the box. Constipation is another condition that can cause litter box avoidance.

If your stray cat is persistently avoiding the litter box, take them to the vet right away. Diagnosing and treating any underlying medical conditions is key to resolving inappropriate elimination issues.

Preventing Future Strays

One of the most important ways to prevent future stray cat populations from forming is to spay and neuter existing cats. Spaying or neutering cats prevents them from reproducing and adding to the stray population. According to studies, targeting at least 70% of the stray cat population for spay/neuter can lead to significant reductions over time (https://www.veterinary-practice.com/2022/study-reducing-stray-cat-populations).

Many local humane societies and rescue organizations offer low-cost spay/neuter services or clinics specifically for community cats and strays. Volunteering or donating to these organizations helps enable more spay/neuter surgeries to take place (https://vcahospitals.com/know-your-pet/managing-feral-cats). Trap-neuter-return (TNR) programs involve humanely trapping community cats, getting them spayed/neutered and vaccinated, and then returning them to their outdoor home. TNR improves cats’ lives while reducing reproduction and overpopulation.

Identifying owned cats can also prevent them from contributing to stray populations if they get lost or abandoned. Microchipping cats and ensuring they consistently wear up-to-date ID tags are proactive ways pet owners can reduce strays. Taking preventative measures through spay/neuter, TNR, and identification are impactful steps individuals can take to address cat overpopulation at the source.


In summary, stray cats may initially avoid using a litter box due to fear, lack of familiarity, or preference for outdoor elimination. With patience and by following a few key tips, you can help a stray cat adjust to using a litter box indoors:

  • Start by confining the cat to a small room with food, water, hiding spots, and a litter box.
  • Use an open, low-sided litter box in a quiet location.
  • Try different unscented litters to determine the texture the cat prefers.
  • Scoop daily and change litter regularly to keep the box clean.
  • Gradually give the cat access to more space over 2-4 weeks.
  • For outdoor cats, transition slowly to being indoors and provide enrichment.
  • Consult a vet if litter box problems persist beyond the adjustment period.

With time and positive reinforcement, most stray cats can adapt successfully to using a litter box. This improves their health and adoptability while preventing unwanted elimination in the home. The keys are patience, attracting the cat to the litter box, and maintaining cleanliness once they start using it regularly.
