Please don't feed Science Diet. I am (also) a vet tech. I finally, finally got my vet to quit selling it. Now he carries the prescription Purina - ugg! It's start, though.
I have had great luck in the past with a suppliment called Bladder Control. Seems like I got it a PetsMart. I have used it in males and females with great results. I use it in conjunction with meds for UTI. Seems to help make the poor babies a bit more comfortable.
I'm planning on trying it on a little girl I have now for spay incontinence.
