Pet's info: Cat | Mixed Breed | Male | neutered | 3 months and 21 days old
My kitten is 4 months old and has been on antibiotics for a week but he is still sneezing a lot with some nose crusties and a watery eye. Does it usually take this long for antibiotics to work?

Poor Finn! Usually, an upper respiratory infection should start to improve within 2-3 days of starting antibiotics - so if he's been on meds for a week now and you don't see any improvement at all, I would recommend taking him back to the vet for a recheck. He may need a different antibiotic, or an anti-viral medication like famciclovir if his current meds aren't working.
