i guess in this matter i'm lucky to only have one sweet kitty mouth to feed. let's see, i buy 2 3.5-pound bags of AlleyCat, and about 10 4-packs of 9lives canned food each month... the Alley cat is about $7 a bag and the 4-packs are $1 each at our commisary so i guess i only spend about $25 on food a month for Boomer. But then add in Litter, toys, and treats and the price goes up dramatically
