Cat peeing in tub.

Species: Cat
Breed: DOMESTIC

Hi, DR. Marie;

Tiger has recently started using the bath tub for his litter box, instead of the litter box. i usually keep them clean, we have 2 other cats as well, and they both use the litter boxes, we have 3 boxes, can you tell me why he is doing this, and how i can get him to stop, and start using the litter box, again?

Dr. Marie replied:

Sorry to hear that Tiger is having problems like this.

Whenever I hear of a case like this the first thing I recommend is to have his urine checked by your veterinarian. Often when a cat has irritation in the urinary tract it can cause them to urinate in unusual places. The bathtub is a really common place where cats urinate when they are uncomfortable.

The urine test will tell you if he has a condition such as crystals, bladder stones, interstitial cystits or an infection.

I wouldn't advise that you wait too long because if this is a medical condition and he gets worse he could end up with a life threatening blockage.

If the tests are normal then you can talk to your vet about behavioral modifying medications such as amitryptiline.

Other things that often help are:


  • Having one more litter box than the number of cats you have.

  • Trying different types of litter.

  • Offering both covered and uncovered boxes.

  • Offering litter boxes in more than one room and at least one on each floor.

  • Using Feliway which is a product that releases a pheromone into the air which greatly reduces cat stress.



I hope things are improving soon!

Dr. Marie.
