Feline Lower Urinary Tract Disease (FLUTD)

Published July 12, 2023

What is it?

Feline lower urinary tract disease or FLUTD describes the following group of symptoms:

  • bloody urine
  • straining to urinate
  • urinating in unusual places
  • licking the urinary opening

To effectively treat FLUTD we need to know what is causing these symptoms.


Possible Causes:

  • Stress - most common cause
  • Bladder stones or crystals
  • Urethral blockage
  • Infection (rare)
  • Others

To determine the cause, we may need to do some tests including urine tests to look for crystals and signs of infection, blood tests to check the kidneys and/or imaging such as x-ray or ultrasound to check for stones.

What’s the treatment?

-pain relief and medication to help with the inflammation and spasm may be prescribed

-if infection is present, our vet may prescribe antibiotics

-if stones or crystals are present, then a special urinary diet such as Hill’s c/d or Royal Canin Urinary S/O may be recommended

-if stress is thought to be the underlying cause, the following recommendations may help:

  • Increasing the number of litter trays - at least one per cat plus one extra
  • Avoiding sudden changes in litter type
  • Increasing water intake - water fountains, additional water bowls of varying shapes and sizes in different locations, wet food etc
  • Encouraging play and environmental enrichment – toys, catnip, cat trees or beds in high places
  • Using Feliway diffuser or spray – this contains pheromones that make cats feel more relaxed
  • Our vet may recommend medications or a special diet to help with stress
