Retrospective evaluation of the incidence of presumed feline urethral obstruction during a prepandemic year compared to a pandemic year.

OBJECTIVE

To investigate the influence of the coronavirus disease 2019 (COVID-19) pandemic on the incidence of urethral obstruction (UO) in male cats.

DESIGN

Retrospective study.

SETTING

One veterinary university teaching hospital and 6 private practice veterinary specialty and emergency centers.

ANIMALS: A total of 24,937 total feline cases presenting to the emergency room (ER) between March 2019 and March 2021.

MEASUREMENTS AND MAIN

RESULTS

Out of 24,937 total cases, 1793 male cats met the inclusion criteria for diagnosis of UO. Of those, 327 cases were identified in which an additional diagnosis of either urolithiasis or neoplasia was made and were therefore excluded. The remaining 1466 UO cases were presumed to be idiopathic urethral obstruction (iUO) caused by feline interstitial cystitis (FIC) alone. Of those, 637 cats presented during the prepandemic year and 829 cats presented during the pandemic year.

KEY FINDINGS: Incidence of presumptive iUO increased by 30% during the COVID-19 pandemic. Total feline emergency caseload increased by 38%. iUO accounted for 6.08% and 5.73% of total feline emergency cases during the prepandemic and pandemic years, respectively.

CLINICAL SIGNIFICANCE: The reported increase in incidence of feline UO is likely due to the increase in overall emergency feline caseload.
