TL;DR: Urinary dribbling is typically involuntary incontinence requiring a veterinary exam within 24-48 hours, but if your cat is straining or unable to urinate, seek immediate emergency care for a potential blockage.
What is urinary dribbling and what causes it in cats?
- Urinary incontinence involves leaking urine involuntarily while walking or resting, occurring without the cat's conscious control.
- Common causes include urinary tract infections (UTIs), bladder stones, or spinal cord injuries.
- Weakened bladder sphincters are a frequent cause of leaking in senior cats.
Is my cat leaking urine a medical emergency?
- The urgency level is typically Medium, requiring a veterinary exam within 24 to 48 hours.
- Critical Emergency: If your cat is straining to go, crying in pain, or if no urine is passing at all, this may be a life-threatening urinary blockage.
How does a photo of the urine spots help my veterinarian triage my cat?
- A clear image allows the vet to see the color of the urine and check for signs of blood (pink or red tints).
- Photos help identify the presence of sediment or mucus.
- This visual evidence provides immediate clues regarding inflammation or infection that might not be obvious during a physical exam alone.
Clinical Context (Merck Veterinary Manual)
Paradoxical urinary incontinence may result from partial urethral obstruction, leading to bladder distention and overflow incontinence with urine dribbling. Inability to urinate can stem from mechanical obstruction by calculi, neoplasms, or strictures; detrusor atony from bladder overdistention; or neurologic disease, potentially causing overflow incontinence. Neurologic causes are categorized as upper or lower motor neuron lesions; lower motor neuron lesions, such as those affecting the sacral spinal cord or pelvic nerve, often present with a distended, easily expressed bladder and urine leakage. Feline lower urinary tract disease, including conditions like urinary tract infection, neoplasia, trauma, urethral plugs, urolithiasis, and sterile cystitis, can also cause dribbling.
