🩺 Urinary Incontinence in Cats – Vet Insights 2025

By Dr Duncan Houston BVSc – Ask A Vet Blog Writer

1. Introduction & Importance

Welcome, caring cat parents! 🐾 In 2025, the term “urinary incontinence” describes involuntary leaking or dribbling of urine in cats. Unlike behavioral litter-box problems, this is a medical concern requiring veterinary attention. With the right care, many cats can have improved comfort and quality of life.

2. What Is Urinary Incontinence?

Urinary incontinence (UI) is the loss of voluntary bladder control—so dribbling while walking, lying down, or sleeping—even though the cat may urinate normally at times.

• Storage failure: Weak bladder or urethral sphincter tone.
• Voiding issues: Neurological or mechanical inability to empty the bladder properly.

3. Common Causes

3.1 Urethral Sphincter Mechanism Incompetence (USMI)

Similar to dogs, cats—especially spayed females and seniors—can develop weakened urethral sphincters, causing leakage when relaxed.

3.2 Neurological or Spinal Trauma

Lower motor neuron injuries (e.g., sacral spine trauma) can lead to overflow incontinence and inability to void normally :contentReference[oaicite:3]{index=3}.

3.3 Urethral Obstruction or Stones

Even after resolving a blockage like uroliths or plugs, residual incontinence is possible as muscles and nerves recover :contentReference[oaicite:4]{index=4}.

3.4 Congenital Abnormalities

Birth defects like ectopic ureters can cause lifelong dribbling. Diagnosis often requires advanced imaging :contentReference[oaicite:5]{index=5}.

3.5 Neurological Disorders & Infections

UTIs, inflammatory conditions, spinal cord disease, or tumors can interfere with bladder control :contentReference[oaicite:6]{index=6}.

3.6 Age-Related Weakness & Cognitive Decline

Older cats may have weakened bladder muscles or incontinence secondary to cognitive dysfunction—a management-intensive situation :contentReference[oaicite:7]{index=7}.

4. Recognizing Signs

• Wet fur around the vulva, prepuce, or tail.
• Urine puddles while resting or walking.
• Litter box used normally—then accidents elsewhere.
• Urination while asleep or not crouched.

5. Diagnostic Approach

Your veterinarian will perform:

1. Detailed history & physical exam (including neurological assessment & urination observation).
2. Urinalysis & culture to rule out UTI or stones :contentReference[oaicite:8]{index=8}.
3. Bloodwork checking kidneys, electrolytes, hormones (especially in older cats).
4. Imaging: X-rays, ultrasound, maybe CT/MRI to assess anatomical defects, stones, or spinal lesions :contentReference[oaicite:9]{index=9}.
5. Neurologic & urodynamic tests to distinguish obstruction vs. overflow :contentReference[oaicite:10]{index=10}.

Accurate diagnosis is essential—it drives the treatment plan.

6. Treatment Options

6.1 Medical Management

• Phenylpropanolamine: An alpha-adrenergic agonist that strengthens urethral tone (1.5–2.2 mg/kg every 8 h) :contentReference[oaicite:11]{index=11}.
• Bethanechol: A cholinergic agent enhancing bladder contraction (1.25–2.5 mg every 8 h) :contentReference[oaicite:12]{index=12}.
• Possible combination therapy (e.g., bethanechol + phenoxybenzamine) for mixed dysfunctions :contentReference[oaicite:13]{index=13}.
• Antibiotics: If UTI or cystitis is detected :contentReference[oaicite:14]{index=14}.
• Prazosin or antispasmodics: For urethral or bladder spasms :contentReference[oaicite:15]{index=15}.
• Pain relief: Buprenorphine or NSAIDs for inflammatory causes like cystitis :contentReference[oaicite:16]{index=16}.

6.2 Surgical Solutions

• Perineal urethrostomy: Bypassing obstruction in recurrent cases. Risk of incontinence exists :contentReference[oaicite:17]{index=17}.
• Corrective surgery: For congenital defects like ectopic ureters.
• Spinal surgery: If neuro lesions are compressive and operable.

6.3 Supportive & Environmental Care

• Express the bladder: For overflow cases—manual expression after consulting your vet.
• Hygiene routines: Clean hindquarters daily and trim fur—Ask A Vet supports these home care routines.
• Water intake: Encourage via fountains and wet diets to support bladder health :contentReference[oaicite:18]{index=18}.
• Litter box setup: Provide low-sided boxes or accessible trays, multiple boxes per cat :contentReference[oaicite:19]{index=19}.
• Environmental enrichment: Reduce stress to help idiopathic cystitis—provide vertical space, playtime, hiding spots, and use pheromone diffusers :contentReference[oaicite:20]{index=20}.
• Pad/diaper use: Short-term use during recovery—but prevent urine scalding and change frequently :contentReference[oaicite:21]{index=21}.

7. Home Care & Quality of Life

Caring for a leaking cat can be stressful—here are practical tips:

• Use washable pads or pee-liners in favorite spots.
• Bathe as needed—gloves, warm water, mild shampoo, and gentle drying.
• Protect furniture with waterproof covers.
• Maintain routine grooming and hygiene.
• Provide cozy, accessible spaces so your cat feels safe.

8. When to Seek Veterinary Help

• Sudden inability to urinate—an emergency.
• Blood in urine, pain signs (crying, straining), lethargy, vomiting.
• Neurological changes—weakness, tail limpness.
• Worsening or spreading incontinence despite care.
