Urination is a really complicated coordination between muscle tissues and nerves. The bladder and the urethra should work collectively to correctly retailer urine and launch it on the acceptable time. There are two phases to this course of: storage and voiding.

Throughout storage, the bladder is relaxed, permitting it to develop and fill with urine. Muscle tissues within the neck of the bladder and the early urethra stay tightened to maintain urine from leaking out.

When your cat arrives on the litter field, the bladder and urethra should shift gears concurrently. The bladder contracts because the urethra relaxes. This permits urine to go away the physique by the urethra. As soon as empty, the bladder relaxes and the urethra tightens again up.

So what occurs when the bladder and urethra don’t work so seamlessly collectively? Urinary incontinence in cats typically falls into two classes: issues with the bladder and issues additional down within the urethra. Every sort can have a number of causes.^[1]

1. Bladder

Urge incontinence: The sort of incontinence happens when the detrusor muscle tissues within the bladder wall contract uncontrollably and intermittently. The bladder usually doesn’t have a chance to fill.

The stress within the bladder physique finally exceeds the resistance of the bladder neck and urethra—so urine dribbles out.

Causes of this sort are normally associated to nerves that connect with the bladder. Spinal wire damage or illness is normally accountable.

2. Urethra

Urethral sphincter incompetence: This pertains to the muscle tone within the urethra that’s supposed to stay tight throughout urine storage after which calm down throughout urination.

The paradox is that there’s truly a blockage current. Practically 70% of cats with non-neurologic incontinence exhibit this sort.^[3]

Causes embody:

• A urinary bladder stone that lodges within the urethra
• A mucus plug that lodges within the urethra (irritation contributes to mucus accumulation and mixes with mineral sediment or grit to kind a plug)

  • Urgency to urinate
  • Extreme licking or grooming of the hindquarters
  • Frequent journeys to the litter field
  • Prolonged durations within the litter field with little or no urine produced

Feline idiopathic cystitis (FIC) is a urinary illness that vets wrestle to deal with successfully. Researchers lately completed a examine involving low-dose radiation remedy to see its advantages for power recurrent bladder irritation.^[4]

Dr. Michael Nolan, a professor of radiation oncology and lead researcher, stated, “You’ll be able to truly deal with arthritis and different inflammatory situations with low-dose radiotherapy and it really works rather well…” He and Dr. Allison Kendall enrolled 15 client-owned cats with FIC of their trial to important success.

Urethral sphincter incompetence may be handled medically. There aren’t any merchandise authorized to be used in cats. However one product, phenylpropanolamine (PPA), could also be used off-label. PPA works by rising muscle tone of the urinary sphincter muscle, holding the urethra squeezed shut and stopping urine leakage.
