Inappropriate elimination (urinating or defecating outside of the litter box, and/or spraying) is the most common behavior problem of older cats but may also occur in cats of all ages. There are numerous causes for this behavior, many of them medical, so a cat who has inappropriate elimination should be examined by a Lange Animal Clinic veterinarian. Laboratory tests may be required to be performed in most cases.
Contributing factors to inappropriate elimination
Medical conditions which result in an increased frequency of urination or defecation may be the underlying cause for this behavior problem. These conditions include: colitis, inflammatory bowel disease, diabetes mellitus, hyperthyroidism, kidney or liver disease, and feline lower urinary tract disease (FLUTD). Medical conditions which cause pain urinating or defecating, or make it difficult for the cat to get in and out of the litter box, may also result in inappropriate elimination. Such conditions include arthritis, FLUTD, anal sac disease, loss of vision, and some forms of colitis. Treatment of these medical conditions may help to resolve this behavioral problem. In addition, using litter boxes with lower sides, placing the litter box in the area in which the cat spends the most time, and increasing the number of litter boxes may be helpful.
Stress can also be a major cause of inappropriate elimination in cats of all ages. Stressors such as moving, changes in routine, holidays, or changes in the makeup of the family can result in inappropriate elimination. The veterinarians at Lange Animal Clinic recommend that reducing these stressors or decreasing their impact on the household will benefit your cat (and probably you, too!). For instance, when moving, attempt to keep the cat in a quiet portion of the home when packing and during the actual moving day. At the new residence, confine your cat to a quiet room at first (probably a bedroom), placing her food, water, litter box and favorite sleeping material (bed, sweatshirt, etc.) in the room. Spend time with her in that room and feed her and clean the litter box at the usual time. Gradually let her become accustomed to the rest of the house.
Cats of all ages may develop an aversion to the litter box or substrate (material inside of the litter box). Some of the litters with a ‘perfume’ or ‘antiseptic’ smell may dissuade some cats from using them. Trying different types of litter including clumping litter, sand, newspaper, and no litter are things that could be helpful.
Litter box location may also cause inappropriate elimination. Some cats may not like where a box is located. It may be located too close to their food or water. It may be in a high traffic area where they cannot have privacy. It may be in an area where they can be easily ambushed by another cat. It may be on a different level of the house than where they spend most of their time. In addition to trying various substrates, also place extra boxes around the house to see if box location makes a difference. There should always be at least one more litter box than the number of cats in the household.
Sanitary conditions may also be a factor as to why your cat is eliminating inappropriately. Some cats are very particular. Some will not defecate in the same box in which they urinate. Others will not go in a box which has been used by another cat. Just as we do not like to use dirty bathrooms, neither do many cats. If the litter box is not cleaned regularly, they may decide to find a different bathroom.
Possible Solutions to Inappropriate Elimination
- Have your cat checked by a Lange Animal Clinic veterinarian for a possible medical condition, and start treatment for the condition if one exists. If the cat is extremely stressed, talk to one of our veterinarians about some medications which may help.
- Place numerous litter boxes around the house. You do not have to use anything fancy: dishpans, large plastic containers, or other items may work just as well. Try a larger litter box, such as a sweater storage box; some behaviorists feel litter boxes are often too small.
- Use different substrates including newspaper, clumpable and nonclumpable litter, sand, sawdust (not cedar), carpet remnants, and no litter at all. Use unscented litter, since many cats do not like the scented kind. If you find the substrate that your cat prefers is not the one you do, e.g., carpet remnants, try slowly converting the cat back to litter. Place a small amount of litter on the carpet remnants the first week, and if all goes well, use more litter each week until you can finally remove the carpet remnants from the box.
- Try different depths of litter. Many people put too much litter in the box. Some cats like only a small amount.
- Clean any soiled areas with a pet safe cleaner such as Nature’s Miracle which is specially designed for use on pet urine and stool. Regular detergents and other cleaners will not break down the urine or feces, and if the cat smells any urine or feces on a carpet or floor, the cat may continue to use that spot to eliminate. Nature’s Miracle does a great job dissolving odor causing compounds from urine or feces in the location where the elimination occurred. In some cases, the carpet or carpet padding may need to be replaced.
- Feed the cat where she is inappropriately eliminating. Many cats will not urinate or defecate in the area in which they are fed.
- Use upside down carpet runners (the ones with the spikes on the bottom), heavy plastic, aluminum foil, double-sided tape, motion detectors, pet repellents, or scat mats to limit her access to the area where she inappropriately eliminates.
- Take your cat to the litter box frequently, and if she uses it, praise her, or even give her a treat.
If you catch your cat in the act of urinating or defecating outside of the box (or even using the digging motion), use a remote correction. This generally means doing something that will startle her. Tossing a pop can with a few coins inside of it and taped shut near the cat (but not at her!) may get her to stop. It is best if she does not associate you with the correction, but thinks it ‘comes out of the blue.’
Do NOT punish the cat. Punishing the cat, including rubbing her nose in the soiled area will not help, and will probably increase the stress on the cat. In some situations, it may be helpful to confine the cat to a small room with food, water, toys, bed, and litter box. Once she is using the litter box in the smaller area, gradually allow her into larger areas of the house.
