A urinary blockage happens when a cat, usually a male, can't pass urine. It's a life-threatening emergency. Signs include straining in the litter box, crying, frequent trips with little or no urine and licking the genital area.

If you think your cat is blocked, call us or come in right away. Treatment usually includes sedation, a urinary catheter to relieve the blockage, IV fluids and hospitalization, followed by a plan to help prevent it from happening again.

Why Male Cats Are at Higher Risk for Urinary Blockages

Male cats have a long, narrow urethra, the tube that carries urine out of the body. Small crystals, tiny stones, mucus plugs or inflammation can easily get stuck and block the flow. Female cats have a wider urethra, so blockages in females are rare.

Several factors can raise your cat's risk. These include stress, a mostly dry food diet, low water intake, obesity, an indoor and inactive lifestyle and a history of bladder inflammation. When a cat cannot urinate, toxins and potassium quickly build up in the blood. Within a day or two, this can affect the heart and become fatal. That is why a cat straining with little or no urine always needs to be seen right away.

Helping Prevent Another Urinary Blockage in Your Cat

Cats who have been blocked once are at risk of blocking again, especially in the first weeks after treatment. Your vet will recommend a prevention plan, which often includes:

  • A prescription urinary diet to help dissolve or prevent crystals
  • More water in the diet, such as wet food or a water fountain
  • Clean, easy-to-reach litter boxes in quiet locations
  • Reducing stress at home with routine, play and hiding spots
  • Keeping your cat at a healthy weight
  • Watching litter box habits closely every day

If your cat starts straining again, call or come in right away. Do not wait to see if it passes.

Blocked Cat Treatment: Frequently Asked Questions

How long can a cat survive with a urinary blockage?
A fully blocked cat can become critically ill within 24 to 48 hours, and sometimes faster. Toxins and potassium build up in the blood and can stop the heart. If your cat is straining with little or no urine, treat it as an emergency and call or come in right away.
How can I tell if my cat is constipated or blocked?
Both can cause straining in the litter box, which makes them hard to tell apart at home. Check the box for urine clumps. If you see small or no clumps, assume a blockage and get your cat seen right away. Your vet can feel the bladder to tell the difference.
How long will my cat stay in the hospital?
Many blocked cats stay in the hospital for a few days with a urinary catheter and IV fluids while the bladder recovers and bloodwork returns to normal. The exact time depends on how sick your cat was and how quickly they improve. Your vet will keep you updated.
Can female cats get urinary blockages?
It is rare, but female cats can have urinary problems such as bladder inflammation, stones or infections. These often cause similar signs, like straining and frequent trips to the litter box. Any cat with these signs should be seen by a vet promptly.
