Urinary blockages in cats—especially male cats—are medical emergencies that require immediate attention. Without swift intervention, a blocked cat can decline rapidly, with complications such as kidney failure, bladder rupture, or death occurring within 24–48 hours. At Woodland Springs Veterinary Hospital in Fort Worth, Texas, we want every cat owner to feel confident in spotting the signs and knowing what to do.

What Is a Urinary Blockage?

A urinary blockage, or urethral obstruction, occurs when something—usually crystals, mucus, or urinary stones—blocks the urethra, the tube that allows urine to exit the body. This condition is most common in male cats due to their narrower urethra and can quickly become life-threatening.

As urine backs up, the bladder becomes painfully distended and toxins build up in the bloodstream. Untreated, this can cause organ failure or rupture of the bladder.

Signs Your Cat May Have a Blocked Bladder

Recognizing the early signs of a urinary obstruction can save your cat’s life. Contact us immediately if you notice:

  • Straining to urinate with little or no urine output
  • Frequent trips to the litter box without success
  • Crying out or showing pain when trying to urinate
  • Excessive grooming of the genital area
  • Bloody urine or strong-smelling urine
  • Lethargy and hiding behavior
  • Vomiting or loss of appetite

Many of these symptoms can be mistaken for constipation, so when in doubt, call Woodland Springs Veterinary Hospital or your nearest emergency clinic.

What Causes Urinary Blockages in Cats?

The most common causes include:

In many cases, diet, hydration, stress, and genetics all play a role. Obesity and inactivity also increase risk.

What to Do If You Suspect a Blockage

Immediate Action Steps:

  1. Stay calm—your cat is likely already stressed.
  2. Do not attempt to treat at home—this is a medical emergency.
  3. Call us at Woodland Springs Veterinary Hospital and head to the clinic immediately.

The longer a blockage goes untreated, the greater the risk of permanent damage.

How We Diagnose and Treat Urinary Blockages at WSVH

When your cat arrives at our hospital, we’ll begin with:

Treatment May Include:

  • Urinary catheterization to relieve the blockage and drain the bladder
  • IV fluids to flush toxins and restore hydration
  • Pain relief and anti-inflammatory medications
  • Antibiotics if infection is present
  • Surgery, such as perineal urethrostomy (PU), for cats with recurring obstructions

FAQs About Urinary Blockages in Cats

Q: Can urinary blockages be cured completely?
Some cats recover fully after one episode, but many require long-term management. With proper diet, hydration, and veterinary care, recurrence can often be minimized.

Q: Are certain cats more at risk?
Yes. Male cats, overweight cats, and those prone to stress or eating dry-only diets are more susceptible.

Q: How fast does a blockage become life-threatening?
Very quickly—within 24–48 hours. Never wait and see if your cat can urinate. Always call a vet.
