My cats been on antibiotics for 3.5 days now for uti and he's still crying a bit when urinating in his box. Good sized urine clumps though. When should I expect him to stop doing that?

I'm sorry to hear that Duck is still so uncomfortable! Most cats show significant improvement with respect to their UTI signs within 2 days of antibiotic treatment. Since Duck is still vocalizing in the litter box, his infection may be resistant to the antibiotics being used. I recommend calling his vet because it may be necessary to perform a urine culture to determine to which antibiotics his infection is sensitive. Continue monitoring the size of his urine clumps and go to an ER vet if the clump sizes become significantly smaller or if he stops urinating altogether. I hope that Duck feels better soon!
