Most pet store clerks are totally clueless about feline nutrition, and this guy was clearly no exception. Take the TOTW back and say your cat won't eat it. Then pick up some cans of quality wet food instead and stick with that.
You can use human probiotics from a health food store. They come in capsules that you sprinkle into the wet food. Most have to be stored in the fridge. A good one to look for is Natural Factor's Ultimate Multi or 12/12. Has a wide variety of organisms and is high potency, with minimal dairy.
