Urinary tract stones in cats

Urinary tract stones occur in cats in a broad variety of sizes. Even the smallest, semolina grain-sized stones can lead to significant problems.

So-called urethral plugs, which are comprised of mineral-based material, can also cause intense pain. Both male and female cats can get urinary tract stones, they are not more prevalent in one sex than the other. The stones can particularly accumulate in castrated animals - both male and female.

Urinary tract stone symptoms

If your cat is suffering with urinary tract stones or urethral plugs, the following symptoms can be observed: 

  • Aggression
  • Frequent visits to the litter tray, passing only small volumes of urine or no urine at all
  • Yowling whilst using the litter tray
  • Blood in the urine
  • Frequent licking of the genital area
  • Uncleanliness (in some cases)
  • Foul smelling urine in some cases

Therapy for urinary tract stones

If your pet shows any of the typical symptoms, you should see a vet as soon as possible. The vet can then investigate whether it is simply a ‘harmless’ urinary tract infection or whether urinary tract stones are the cause. By using ultrasound equipment and testing the urine, in some cases the vet can quickly determine whether the cat has urinary tract stones, and if so, which type. Struvite and calcium oxalate stones are the most common type of urinary tract stones in cats.
