at 3 oz a day (12 pound ) it is enough for 2 months, so $15 a month, like Craftlady said, not $30.


They have 12 lbs bags for $26.99.
This size bag should last you 2 months feeding one kitty.
1/4 - 1/2 cup


May vary according to activity level of cat.
A standard 8 oz. liquid measuring cup = 4.7 oz. Wellness Dry Kitten Food 1/4 to 1/2
I am not sure the age of the kitten, but here is the feeding amount for babies. So it seems like it will be a lot less than you had figured.
