Hello there,
try not to worry to much, your diet can be the reason of the cloudy urine alot of different foods change your urine, if its a uti there is normally (sorry for the graphic detail) bits floating in the urine, shes also on medication to at the moment and it might be her body's way of getting rid of the current infection she has. but if your still worried approach you GP, thats what they're there for.
Love and hugs
xx
