Cat Urinary Tract Infection Recognition

True bacterial urinary tract infections are less common in cats than in dogs but require prompt recognition and treatment when they occur.

Key Facts

True bacterial UTI is much less common in cats than in dogs — only about 1-3% of cats with urinary signs have culture-positive UTI.
Middle-aged to older female cats and cats with diabetes or other systemic disease are at highest risk.
Signs include straining, increased frequency, haematuria, and licking at the urogenital area.
Urine culture is essential for antibiotic selection — empirical treatment without culture risks inappropriate drug choice.
Most young, otherwise healthy cats with urinary signs have feline idiopathic cystitis, not bacterial infection.

Welfare Considerations

Cats with bacterial UTI experience discomfort from mucosal inflammation, urgency, and the repeated pain of trying to urinate. The chronic nature of untreated or inadequately treated UTI leads to ascending infection potentially reaching the kidneys (pyelonephritis), causing serious welfare compromise. Conversely, over-treating cats with FIC as if they had bacterial UTI with antibiotics is both clinically inappropriate and contributes to antimicrobial resistance. Accurate diagnosis through urine culture guides appropriate treatment and protects both individual cat welfare and broader public health through responsible antibiotic use.

What You Can Do

Request urine culture rather than accepting empirical antibiotic treatment for urinary signs in your cat.
Provide a fresh, clean urine sample (cystocentesis is gold standard) for accurate culture results.
Complete prescribed antibiotic courses fully to prevent resistance development and relapse.
Discuss underlying systemic conditions (diabetes, CKD) that predispose to UTI with your vet.
