Cat question?What would you like to ask?Can hamster bathing sand be used for cats?

i have a long gone hamster , and i still have a bucket of hamster bathing sand ( on the back of plastic bag says that: cleans fur, kills flee , doesn't harm thier nose/eyes, makes their fur smooth...) so i was thinking , why not give it to my cat. cuz it seems such a waste . i think their not cats, maybe kittens. cuz they're very naughty and playful. so should i. cuz i see my hamster also s.h.i.t in there so maybe cats do 2.
