for complicated UTI. This recommendation is based
on expert opinions. There are no prospective studies evaluating the duration of antimicrobial treatment of
feline UTI.In cats with indwelling urinary catheters, prophylactic antimicrobial therapy for prevention of UTI
is never indicated. A urine sample (ideally collected by cystocentesis) should be submitted for culture at the time of catheter removal and possible infection treated based on results of culture/susceptibility testing. So far, the signi cance of subclinical bacteriuria in dogs and cats is not fully understood, and it is not known whether treatment of cats with asymptomatic bacteriuria is always bene cial. In a recent study, 67 nonazotemic cats > 7 years had urine cultures performed on up to 5 occasions over a three-year period (11). The incidence of subclinical bacteriuria varied between 10 and 13%. Cats with positive urine culture were not treated with antimicrobials. An adverse association between subclinical bacteriura and survival was not identi ed in this study population. Asymptomatic bacteriuria is a common  nding in healthy women and in women and men with comorbidities. Several randomized clinical trials have identi ed no bene ts of antimicrobial treatment in asymptomatic individuals. It is, however, not possible to extrapolate these results to cats and dogs. So far, there are no prospective studies in cats with subclinical bacteriuria. Current guidelines recommend considering treatment
for asymptomatic bacteriuria in patients at high risk of ascending or systemic infections, such as chronic kidney disease, systemic immunosuppression or diabetes mellitus.
