LITTERBOX PROBLEMS

Ah, the smell of summer is in the air.  Backyard barbecues, lilacs, fresh mown grass and cat urine.  PHEW!!  Yes, cat owners often have to take the bad along with the good.  If you're tired of finding wet spots with your bare feet and stains all over the house, take heart and read on.  Here are solutions that can help guide your errant pussycat in the direction of his litterbox.

Housesoiling is the most common behavior problem for which cat owners seek my help.  The typical cat's convenient habit of disposing of urine and stool in the litterbox helps make it a popular indoor pet.  On the other hand, the indiscriminate elimination habits of some cats have contributed to their demise.  It's very frustrating to live with an otherwise loving, wonderful pet, but have to cope with the disagreeable problem of housesoiling. 

The number of reasons why a cat might begin eliminating outside its litterbox  seems to be limited only by the pet's imagination.  Uncovering the motivation often takes some real sleuthing.  The first  fact you want to pin down is whether the cat is spraying vertical surfaces with urine or eliminating inappropriately on horizontal surfaces.  Spraying occurs when a cat backs up to an upright surface and directs a stream of urine toward it.  This is a marking behavior. 

Marking is likely to occur when the pet feels as if its territory is being invaded, or if there is something in the pet's life that makes it anxious.  Neighbor cats visiting in the yard or too many cats in the home can trigger this kind of problem.  Spraying increases from 25% in single-cat households to 100% in households with more than 10 cats. Unneutered males or females in heat are the individuals most likely to spray, although some neutered cats  will take up this nasty little habit.  Studies have shown that as many as 10% of castrated male cats and 5% of spayed female cats take up spraying on a frequent basis as adults.  The objects that are commonly sprayed include doors, walls by doors or windows, new objects in the house, and furniture.  One owner sought my help because the cat was spraying the new roommate, much to her dismay.

The tendency to spray is influenced by factors pertaining to the individual (hormones, personality), environmental stimuli that are upsetting to the cat (new roommate, new cat in the neighborhood, remodeling, moving) and its relationship with the owners (change in the work schedule, absences from home, spending less time with the pet, inappropriate punishment).  Sometimes, just the suggestion that another pet has invaded its territory can cause the pet to spray.  For example, if a visitor has cats at home, a cat may spray the visitor's coat when it smells the odor of the non-resident cats.  One patient of mine started spraying around the fireplace when firelogs that were sprayed by roaming cats were brought inside the house.

Inappropriate elimination involves the act of squatting to defecate or urinate on horizontal surfaces outside the litterbox that are unacceptable to the owner.  Housesoiling that occurs as a squatting behavior happens with an almost equal frequency in females and males.  Horizontal surfaces may be soiled in a variety of areas, or the pet may develop a specific location preference.

If the cat suddenly starts urinating and defecating outside the box, it's highly likely that something about the litterbox is unacceptable to the pet.  The physical accumulation of waste, organic odor, disinfectant odor, pain associated with elimination, unacceptable litter or a negative experience associated with the litterbox may cause the pet to avoid it.  Litter brands containing perfumed scents are possible culprits.  The box may be in an area the cat doesn't like.  There may be too much traffic through the area, or the area may be associated with something aversive that happened to the cat (a place where it was medicated, disciplined or frightened).  If the pet has been severely punished for any reason, it may start eliminating in secluded areas in order to avoid family members.  Some cats will eliminate outside the litterbox simply because they've found another area or surface that is preferable.  If the cat consistently defecates in the box, but urinates elsewhere, or vice versa, the problem probably isn't caused by an undesirable litter, litterbox or box location.  Likely causes are medical problems, new surface preferences or new location preferences.  Other causes of inappropriate elimination include a need for privacy and medical problems (bladder infection, constipation, diarrhea, diabetes, kidney disease, arthritis, senility).  Be suspicious of constipation or colitis if an older pet suddenly stops defecating in the litterbox, but continues to use it for urination. 

Medical problems are common causes of housesoiling.   Watch for an increase in frequency or volume of urination; straining or discomfort when eliminating; the presence of blood in the urine; and very hard stools.  A visit to your veterinarian is very important.  A urinalysis, fecal exam or blood tests may be recommended.  All attempts at behavior modification will fail if an underlying medical problem is not corrected.

In some cats, the act of eliminating on horizontal surfaces can be a marking behavior caused by the same stimuli that cause spraying.  The most common cause is an increased number of cats in the household or neighborhood.  Emotional problems, such as a rocky relationship with a family member, owner absences or fear can trigger housesoiling.  If the cat is urinating on top of specific items, like a family member's clothing, bed or favorite chair, you will want to be sure to explore an anxiety-motivated problem.  These problems are often tough to diagnose, especially if the problem is only manifested intermittently.  Keeping a diary may help.

Sleuthing

Uncovering the early causes of a long standing housesoiling problem can be  a challenge.  A good memory and input from all family members are essential in pinpointing the motivation for the unacceptable behavior.  Be sure that you know for certain which cat is missing the box.  In a multi-cat household, separation may be necessary to find the culprit.  You can't just blame the indiscretions on whomever looks guilty.  To pinpoint the cause, you'll want to think back to when and where the problem began, and if there were any changes in the pet's environment that were associated with the appearance of the problem. 

Diagram the house with litterbox placement and soiled areas noted.  If territorial marking is the motivation, you may discover clusters of soiled areas around windows or doors in the house near where outdoor cats visit.  The objective is to uncover the factors that motivate the undesirable elimination behaviors.  You need to keep in mind that the factors that contributed to the initiation of the housesoiling may be different from the factors that are maintaining the behavior.  For example, a sudden change to a brand of litter that was unacceptable to the pet may have caused it to avoid the box and eliminate on the living room carpet.  After a while, the cat may decide that a rug in the living room is good or better than litter in the bathroom.  It will continue to eliminate in the living room even though the owner switches back to an acceptable brand of litter.  In this case, the initiating factor was a litter brand change, the maintaining factors are new elimination preferences.  It is important to know the maintaining factors in order to curtail the on going problem.  Uncovering the initiating factors will help you learn what to do or avoid in order to prevent the problem from recurring.

Is there hope?

The chances of success depend on a number of factors: the duration of the problem; the number of areas soiled; the number of different surfaces soiled; the ability to control the stimuli that trigger marking behavior; the temperament of the pet; whether the pet was ever trained to use a litterbox; and the patience, ability and willingness of the family to commit to working with the pet.  As you might imagine, if you have a problem in which Mr. Leaky Pipes has been urinating all over the house, on carpet, linoleum and furniture for the past five years, you’ve got a major problem.  If he also doesn't get along with certain family members who are apathetic about the problem, then you're up the creek with plenty of piddle, but no paddle in sight.

Correcting the problem

The two main approaches to eliminating urine marking include altering the stimulus and altering the cat's normal response to the stimulus.  If outdoor cats are the stimulus for spraying, the owner should consider discouraging their visits with a water hose or humane booby traps.  Anything in the yard that might attract roaming cats should be removed (bird feeders, garbage, food, etc.).  Besides removing the stimuli, the owner can remove access to the stimuli.  The spraying cat should be kept out of windows or out of rooms that permit it to view outdoor cats.  Drapes can be closed.  Window sills can be modified.  Chairs near windows on which the cat perches can be moved.  What the cat doesn't know won't hurt him.  Urine odor should be cleaned from around doors and windows.  If other cats in the household are contributing to the problem, they should be separated.  In some cases, the number of cats in the home may need to be reduced.  Some individuals will spray less indoors if they have more access to the outdoors.  Other do better if kept inside more.

Neutering is very successful in curbing spraying behavior because it reduces the pet's response to anxiety-provoking stimuli in the environment.  In most cases, neutering should be done as soon as possible.  Ninety percent of males and ninety-five percent of females will not spray following castration or spaying.  Medication may often be required to control spraying behavior.  Antianxiety medication may be prescribed by your veterinarian if you have a particularly difficult time getting the spigot turned off.  Medication does not work for every cat.  You should expect a decrease in the marking behavior within one to two weeks if the pet is going to respond.  Once you see some progress, your veterinarian will probably want you to slowly decrease the dosage.  Now that newer, safer medications are available, hormones are infrequently used for spraying problems.  Always be sure to discuss potential side effects with your veterinarian.

Treatment of inappropriate elimination problems involves three major considerations:  removing the cause, reestablishing the habit of litterbox use and preventing the cat from returning to previously soiled areas.  If the housesoiling occurs because the cat dislikes something about the litterbox or its location, the box may need to be moved, an acceptable brand of litter must be found, the box may need to be cleaned more often and rough handling in the box must be stopped.  Changing the depth of the litter or removing a plastic litterbox liner may help in some cases.  Switching to a sand/potting soil mix or one of the fine clumping litters may also be helpful.  The results of a study of feline litter material preferences suggest that an important factor in a cat's preference for litter material is its texture, granularity, or coarseness.  The cats in the study showed a definite preference for a finely textured clay litter.  Any new litter or litterbox substrate should be introduced in an additional box in case it happens to be one the pet dislikes.  As a rule of thumb, you should provide at least one box per cat.  The boxes should be scooped once or twice daily and emptied at least once each week.  Scalding hot water should be used instead of harsh smelling disinfectants.  If disinfectants are used, the box should be dried in the sun and out of operation for at least twenty-four hours.

If the cat prefers hard surfaces, try using an empty litterbox or food tray.  Gradually add litter to the container.  Some cats appear to need privacy.  For these cats, you can place an open-ended cardboard box over the litterbox or purchase a covered box.  Another solution is to put a cat door in the door to a closet or storeroom.  This will also protect the pet from being bothered by pesky children or an annoying pet dog.

To reestablish a consistent habit of using the litterbox, the cat should be confined to a small area with the box and only allowed out when it can be supervised 100% of the time.  When confined to a relatively small area, most cats seem to prefer to eliminate in the box rather than soiling the floor.  It's then a matter of confining the cat long enough for a consistent habit to become established.  This may take several weeks or more.

Don't forget about the pet during the confinement period.  Have frequent play and social sessions.  If the cat still refuses to use the litterbox when confined to a small room, the confinement area should be changed to a large cage.  If you've tried a variety of materials in the litterbox and the pet won't use the box, a perch or shelf should be added inside the cage.  The floor should be covered with litter, which will force the pet to use it for elimination.  Then, the litter on the floor can gradually be removed and replaced with a litterbox.  Food rewards may help when given immediately after the cat finishes eliminating in the box.  Once the cat has used the litterbox in a confined area for an appropriate amount of time, you can begin to allow more freedom in the house.

Previously soiled areas can be safeguarded by placing safe booby traps, food bowls, bedding or toys in the areas.  Plastic, foil or double-stick carpet tape can be used to protect specific areas.  You may need to experiment.  Each cat is an individual regarding surface preference for elimination.  A surface that repels one cat, may attract another.  An inch of water in the bathtub or sink will curb elimination there.  Access to the soiled areas can be denied by moving furniture or closing doors.  In some areas, such as the corners of the basement, it may be prudent to place a litterbox where the cat has been soiling.

Removing the odor is important.  Products that are formulated specifically to work on feline stool and urine odors should be used.  These products need to make contact with the organic material and, in most cases, an ample amount should be poured on carpeting and porous surfaces, rather than lightly sprayed.  A 50:50 mixture of white vinegar and warm water will do a satisfactory job if nothing else is available.

Some cats are extremely sensitive to changes in their environment and urinate inappropriately in response to minor changes.  You need to realize this and do your best to keep things constant.  This is not always possible.  When situations occur that are likely to upset the cat, it may need to be confined, supervised or placed on medication. 

Punishment is the least effective tool to control this type of problem.  Punishment may make things worse if anxiety or fear is an important component of the problem.  Under no circumstances should you swat or physically punish the pet.  Rubbing the pet's nose in the mistake is a definite "no no" as is roughly handling the pet and placing it in the litter box.  If you catch the pet in the act of eliminating in an inappropriate area, squirt it with a water gun, toss an object near it, or make a loud noise so it will learn to associate something negative with the behavior.  Any  type of punishment should only be given during the behavior or within one to two seconds after the behavior ceases.  If you don't catch your pet in the act, don't even scold it.  Remember that it's very important that your cat not associate the punishment with the person doing the punishing, or the bond between you and your pet will quickly deteriorate.

If these suggestions don't help, talk to your veterinarian about seeking the help of a qualified pet behavior consultant in your area.
