"i wish they made kibble for humans" that's grape nuts, you don't remember what grape nuts looks like but I can assure you grape nuts is human kibble.
have you ever heard of Studentenfutter?
It's got kibble in the name, is meant for human consumption (allegedly) AND it contains actual grapes (ok... got me, they're raisins) AND ACTUAL NUTS!
it's mostly just hazelnuts, almonds and raisins...
