Below you will find helpful information on the causes and treatment for urine marking in felines.


  • Limited access to the outdoors.
  • Not having enough litter boxes. The number of litter boxes should equal the number of cats plus one.
  • Dirty litter boxes. Scoop daily and clean weekly.
  • Previous urine marking. Always clean with an enzymatic cleanser.


  • Maintain an environment with plenty of litter boxes, food, water, resting areas, perches, and hiding areas.
  • Some cats respond to seeing cats outdoors by marking, so blocking access to the window or covering the window may help. Use of motion-activated devices such as sprinklers may keep outdoor cats away from your property.
  • Pheromones can be used to treat urine marking as well, for example Feliway. A double-blind, placebo-controlled trial found that, after 4 weeks of treatment, cats exposed to pheromones had a significantly lower mean level of marking than cats treated with a placebo.
  • There are no drugs currently approved for use in treating feline urine spraying. Any medication prescribed should be considered extra-label usage.
