Urinary Blockage in Cats


Urinary blockage, first and foremost, is considered to be a veterinary emergency.

It occurs when the urethra (the tube that carries urine from the bladder to the outside of the body) becomes partially or fully blocked, which makes it difficult or even impossible for a cat to empty their bladder.

This blockage is usually caused by a buildup of material such as urinary stones, urinary crystals, mucus, blood clots, and/or bacteria. When these materials prevent the urethra from passing urine, a series of complications can occur. Since urine contains metabolic waste products that the body needs to eliminate, the act of urination is necessary for these metabolic wastes to be removed. If urination is prevented from taking place, these metabolic wastes understandably will build up. The pressure caused by the accumulation of urine within the bladder can also be damaging to the kidneys; the bladder may even become so full to the point where muscle function is lost.

Both male and female cats may develop urinary blockages, however male cats have narrower urethras, which puts them at greater risk. Signs of urinary blockage are the same regardless of gender, and cats may show some or all of the associated clinical signs.

If your cat is experiencing any of the following, it is important to seek veterinary assistance immediately…

  • Straining to urinate (trying to urinate and not passing any urine or passing very small amounts of urine)
  • Painful urination (crying or howling in pain when trying to urinate)
  • Inappropriate urination (urinating outside of the litter box)
  • Blood in the urine
  • Hiding/lethargy
  • Resenting being touched in the abdominal area
  • Refusing to eat

The intensity of these signs may vary, especially as the condition progresses. If left untreated, it can unfortunately become life-threatening in a very short amount of time – this is why it is so important that you be aware of the signs to look out for. If you notice your cat exhibiting any of these symptoms, seeking immediate veterinary assistance is critical.
