URIs may be caused by viral or bacterial means, so your cat may continue to have the virus live dormant in her body even once her symptoms have stopped. If her symptoms have stopped and the antibiotic course is finished, it is likely safe, however it is always best to confirm with the veterinarian that examined and treated your cat as they will know her history and prognosis best. If she is still having symptoms even after a round of antibiotics it is best to bring her back into your vet for a recheck examination.
