Why Is the Cat Refusing to Use the Litter Box?

Although cats usually have a natural inclination to use the litter box, there may be times when your cat won't. The problem can be an easy fix, or it can be the sign of a serious condition.

  1. Urinary Tract Infections

    • A cat with a urinary tract infection will often not use the litter box because he has associated a litter box with pain. A cat with a urinary tract infection may frequently strain to urinate but the amount of urine passed will be small. Blood may be present in the urine. He may also start using cooler, hard surfaces to urinate on, such as a bath tub or tile flooring.

    Other Urinary Problems

    • Besides urinary tract infections, your cat could be experiencing urinary stones or a urethral blockage. These diseases are more common in male cats than females. Stones are typically removed by surgery. A urethral blockage can become fatal very quickly if not treated.

    Changes

    • If the environment has changed, he may be re-marking his territory, leaving scent marks on carpet or in other various areas around the home. If the litter, box type, location or anything about the box has changed, he may not like it.

    Considerations

    • Consider making a switch if a veterinarian determines your cat is not suffering from a urinary tract infection. Move the box to a different location, use litter that has a similar texture to what she's been using or try a different style of box.

    Dirty Box

    • An unmaintained litter box will encourage a cat to relieve herself elsewhere. Cleaning should be done at least every other day, if not more often.
