According to Wiki Answers: There is 28 grams in an ounce. so that means that their is 1 ounce and 4 grams left over!
The formula to convert 32 grams into ounces
32 g * 1 oz
28.34952313 g = 1.128766782 oz
So being kitty is 10 lbs. I would think 1 ounce would do? Do you have a kitchen scale? Like the kind used for dieting? That might work.
Here is another conversion:

They claim 32 g is 1.13 oz.
But all this still doesn't tell us how many granules will weigh up that amount. Anybody have a diet kitchen scale you can borrow?
