Why Isn’t a Neutered Male Cat Urinating?
📝 Summary
No urination within 24 hours after neutering is normal, wound pain; beyond that, watch for stress-induced cystitis, urinary infection, stones, or even kidney failure, male cats are prone to urinary blockages. Diagnosis needs urine and blood tests plus imaging; treatment ranges from antibiotics and diuretics to stone removal or kidney support.
1 Why a Neutered Male Cat Isn’t Urinating
1. Causes
No urine within 24 hours is usually wound pain and resolves on its own, no worry.
If still none after 24 hours, stress may have caused idiopathic cystitis; see a vet.
Sudden abnormal urination later may mean urinary infection, stones, or even kidney failure. Male cats have narrow urethras and weak drinking habits, burdening the kidneys, so older cats often develop chronic kidney failure, and most urinary disease causes blockage.
2. What to do
Abnormal urination, accidents, frequency, scant or bloody urine, blockage, usually points to the urinary system. Observe the urine for blood, then get a vet workup: blood count, urinalysis, ultrasound, X-ray, and biochemistry, to check for kidney issues or stones.
For ordinary bacterial inflammation, use cefadroxil and hydrochlorothiazide to relieve blockage, cefadroxil fights infection and eases pain, while hydrochlorothiazide is a diuretic that restores normal flow.
Stones need anti-inflammatory, diuretic, and fluid therapy; a blockage may require surgical removal.
Kidney disease is harder to treat, beyond anti-inflammatory and diuretic drugs, add a kidney-support supplement like Shenglibao per the vet’s assessment.
On urinary disease, feed prescription diet if possible, and boost water intake. For other questions, consult a vet.
