The term 'inappropriate urination' is relatively self-explanatory. It
refers to cats who urinate on surfaces and in places that are not considered
appropriate by their owners. Basically, except for the few indoor cats
that use household toilets, it is only considered appropriate for cats to
urinate in a litter box. Urinating on the couch, bed, wall, rugs, and
ceramic tile, or in the bath tub, laundry basket, or kitchen sink is just not
Inappropriate urination is, unfortunately, too common. All of us have
known of cats with this unwanted habit. Many of the cats are labeled as
lost causes and either pushed out the door to become outside cats or given up to
animal shelters. But the vast majority of these cats can be helped.
With a little detective work, the underlying cause can be found. Once the
cause is uncovered, appropriate treatment strategies can be implemented and the
cats can be taught to reuse their litter boxes.
Consider inappropriate urination a message from the cat. Something is
wrong and the cat is letting you know. The cat is not 'acting out', but
asking for help. I have yet to meet a cat that did not, as a kitten, use a
litter box. I have taken in feral cats and kittens ranging in age from one
day to many years, and each and everyone have used a litter box. Even the
youngest, motherless kitten will rapidly grasp the use of a litter box when
placed in one. This is because cats have a natural affinity for sandy
substrates. They want to dig in soil before they eliminate. They do
not naturally choose flat, smooth, or cloth-like surfaces.
So if cats naturally use a
litter box, and then decide to stop, something must have gone wrong. The
cats are not spiteful, angry, or mean; something has gone awry. The list
of problems that can push a cat out of the litter box and towards inappropriate
urination is a long and potentially complicated one. The list can be
divided into management,
medical, and behavioral causes.
Medical reasons include any illness or disease that causes the cat to be in pain
or increases urine production. So a bladder infection, with accompanying
urinary tract pain, can certainly cause the cat to associate the box with the
pain and lead to urination outside of the box. Other causes of pain might
include bladder stones, inflammation, or tumors, as well as arthritis, muscle
disease, or spinal cord pain that interferes with movement in and out of the
box. All painful incidences associated with the box may result in failure
to use it. Additional medical causes would include cognitive diseases that
impair the mental abilities of older cats.

A final category of medical illnesses include all those that lead to increased
urine production, such as kidney disease, diabetes, and thyroid problems.
The greater the urine production, the more often the cat must urinate.
This upsets the cat's routine and soils the box more rapidly than expected,
ultimately causing the cat to abandon the box.
Every single cat that inappropriately urinates should be examined by a
veterinarian as soon as possible. Illnesses need to be caught early in
order for appropriate therapy to work and to prevent the inappropriate urination
from becoming habit. Cats are known to hide disease. Inappropriate
urination may be the cat's only notice to you that the he is sick. Heed
the warning and rule out medical causes before blaming the cat for 'bad
Another major cause of inappropriate urination is poor litter box management
which results in cats having an aversion to the box, the litter, or the
location. These cats may then develop a preference for a different
location or surface. Owners often have boxes that are too small, too few,
too dirty, left in incorrect places, or filled with litter which feels or smells
bad to the cat. No cat likes a small, dirty, noisy box. Your cat's
inappropriate urination may be the cat's method of telling you this. When
purchasing, placing, and filling litter boxes, think of the cat's needs before
Different cats have different needs. Some cats need boxes with low sides
or high sides, or ones that are open-sided or covered with a lid. Some
have aversions to scented litter, or clumping litter, or unscented litter, or
the chemicals in the plastic box. So buying the smallest, covered box for
a 15 pound cat will not work. Neither will buying the deepest,
self-cleaning box for a timid, 1.5 pound kitten. And putting a box down
two flights of stairs may invite trouble from a 19 year old arthritic cat.
While we are on the subject of boxes, litters, and locations, I can pretty well
guarantee that you can cause inappropriate urination by putting a litter box

washing machine that hits the spin cycle just at the cat tries to use the
box. A litter pan near a washing machine or dryer is an invitation for
To prevent litter box aversion, make sure your cat likes her box. Identify
your cat's needs and meet them. Trial and error may be needed to find the
appropriate mix of box, litter, and location; but it's worth the effort in the
long run. Litter type, depth, and fragrance are all variables that can be
adjusted. So try different types of litter, including clumping and
non-clumping, scented and non-scented, and litters made of wheat or paper. Also,
experiment with covered and uncovered boxes, self-cleaning litter trays, and
round or rectangular pans.
Purchase multiple boxes for multi-cat households. The rule of thumb is one
box per cat, plus one extra box. So a household with four cats need five
boxes, preferably in separate locations. This may sound excessive, but it
is much easier to manage the boxes than a cat urinating on the pillows! If
may even be necessary to have different types of boxes and different litters for
the different cats.

Lack of litter cleanliness is a significant cause of inappropriate
urination. Cats do NOT like dirty litter boxes. Their noses work
much better than human noses, so they can detect unpleasant odors that people
ignore. Some cats are so offended by dirty litter that they will even
avoid boxes used by other cats. Some will try to keep their bodies out of
the box and urinate over the edge. Some will gingerly step in the box and
urinate out of it, or urinate just next to the box. These cats are telling
you very clearly that they do not like the litter in the box. They are
attempting to use the pan, but are just too repulsed by the litter to use it
appropriately. If the situation is not remedied rapidly, these cats may
soon avoid the entire litter box.
Heeding the cat's pleas can help prevent inappropriate urination. The
litter pans must be as clean as possible. Daily scooping should be
considered the minimum requirement. It is actually wiser to scoop boxes as
often as they are used, even if this is two, three, or four times a day. I
realize that everyone knows of an owner that only cleans boxes once per week and
the cats are just fine. Do not assume this will work for your cat and do
not get comfortable with this system. At any time an individual cat may
react to a filthy litter pan by choosing to urinate outside of the box. It
is easier to prevent the problem with frequent cleanings than to attempt to
Plastic litter boxes also hold odors, so boxes should be dumped and washed out
weekly. Use a mild detergent, rinse thoroughly, and then dry the box
before refilling. The pans may even need to be replaced periodically, as
it is impossible to get rid of the accumulated odors that eventually permeate
the plastic. Actually, this is a good reason to avoid saving old litter
boxes from previous cats for new arrivals. The new cat can still detect
the odors from the old cat and may refuse to use the old box. So, the
second rule of thumb is that new cats should always get new litter boxes.
Litter box aversion can be prevented with proper planning. Start off
correctly by purchasing fine, unscented litter and placing it one to two inches
deep in a clean box. Most cats like large, uncovered boxes, as the odors
are not trapped in the box and the cat can see out of the box. Place the
box in a quiet area that is separated from the food area and away from
machinery. Pick quiet, easy-to-access locations. Avoid damp, dank
spots (wet basements) that hold odors and keep the litter moist. Avoid
litter box liners, if possible, as many cats dislike them. Keep the box
clean and dry, change litter as needed, and make sure that all the cats have
easy access to all the boxes.
If all litter box management issues and medical issues are handled, and a cat
demonstrates inappropriate urination, behavioral causes need to be
explored. It this is the case, it is important to seek help quickly.
The longer the problem continues, the more difficult it is to treat and the
longer the problem takes to resolve. Cats will rapidly develop preferences
for inappropriate places because the surface and location are more pleasing than
the litter pan. The problem then becomes more difficult to solve, as the
cat now has both a behavioral issue and a preference for the wrong spot.
Behavioral issues are as varied as cats. Often the detective work involves
an in-depth knowledge of cat behavior. Owners may not be able to identify
the problem and may need help from outside sources. Pet behaviorists,
veterinarians, and board-certified veterinary behaviorists can be of great
help. They may interview owners, examine the cat, and even visit the house
to uncover the root of the problem. A common example of behavioral issues
would be a cat that is too frightened to use the box because other cats
terrorize her both in and out of the box. Another example is a cat that
suddenly becomes territorial when he sees a stray cat outside. The indoor
cat cannot reach the outdoor cat to claim his territory, so he urinates near the
door. Other cats have been known to stop using their boxes when antique
furniture or old carpets stained with urine from previous animals are brought
into the house. Others are upset by new pets, new adults, or new
babies. Some are reacting to tension or fighting within the
household. The list goes on and on.
to the specific cause and can be a simple as adding additional litter boxes,
closing the blinds so a cat cannot see outside, or getting rid of old, soiled
furniture and carpets. Others standard 'fixes' include using enzyme
cleaners to clean up any accidents and remove odors. In addition, it is helpful
to cover inappropriate areas with plastic carpet runners, sheets of plastic, tin
foil, or other items with textures that the cats find unappealing. Make
sure to close doors to keep cats away from rooms and furniture they wish to use
as litter box. Cover the bases of plants with tinfoil or wire mesh to keep
out curious cats. The use of soothing pheromones, such as Feliway, may
also be helpful for cats suffering from anxiety. Some cats also respond
positively to special litter attracting agents made from soil and herbs.
Finally, some cats need anti-anxiety medications available from veterinarians.
Punishment should not be used. Hitting, screaming, and rubbing the cat's
nose on the soiled areas is ineffective and inhumane. These actions will
increase the cat's anxiety, teach it to run from you, and most likely make the
problem worse. The cat will not connect your behaviors with his actions
and simply learn to avoid you, along with the litter box. In addition,
your behavior may increase the cat's nervousness and create additional troubles.
If your cat is urinating inappropriately, seek creative management solutions,
A similar, but different problem involves cats that spray. The issue with
these cats is not the use of the litter box, but urine marking. Cats that
spray inappropriately deposit small drops of urine in a specific area. Usually
they are standing when they do this and back up to a spot, wiggle their tail,
and release small amounts of urine on vertical surfaces. Cats that spray
are communicating with other cats. They may be announcing their presence,
making or keeping their territories, or looking for a mate. Most cats that
spray are un-neutered males. A few are un-spayed females, spayed
females, and neutered males.
Because spraying is a territorial sign, the incidence of this behavior goes up
in multi-cat households or houses with feral cats roaming the yard. Cats
also spray if they think their territory is invaded, so a new cat, baby,
roommate, furniture, or even carpeting may trigger spraying. Illness, lack
of appropriate exercise, isolation, and inactivity may also lead to spraying.
Treatment for spraying is similar to that for inappropriate urination, with one
notable exception. Since hormonal influences drive intact male cats to
spray, any intact male cat that sprays should be neutered immediately. The
sooner this is done, the sooner the problem will resolve. Since indoor
cats are typically neutered, this should not be a problem for most owners.
Other treatments include separating the cat from the preferred spraying area,
covering the area with plastic or tinfoil, and the use of pheromones or
medications to ease anxiety.
Territorial issues can be helped by reducing an indoor cat's ability to see
outdoor cats and by increasing the space allotted to interior territories.
Obviously, you cannot make a house bigger. But you can increase the space
each cat calls his own. Make room vertically by clearing off shelves
and adding cat furniture that allows the cat to climb up. Add horizontal
hiding places with boxes, a few open drawers or closets, and cat furniture.
Anything that allows the cat to move into more areas will decrease pressure to
defend the territory and may reduce spraying.
The bottom line is that a variety of environmental, behavioral, and medical
causes can lead to inappropriate urination and/or spraying. It is up to
the owner to take immediate action to uncover the cause, eliminate it, and take
appropriate steps to get the cat back into the box. This may take time,
consultation with professionals, changes in household management, and
considerable effort. The good news is that the vast majority of cats can
