Thanks! I use all kind of plastic bottles as funnels in the kitchen.
I also "rolled up" some 8.5" x 11" card stock, kind of "at an angle" to make big funnels for pouring dry cat food.
I did the same thing with much smaller sqaures of card stock or stiff glossy magazine covers. those make nice tiny funnels for spooning seeds into small Ziplok baggies. They push right into the Ziplock, which I set inside a plastic pill bottle weighted down with pennies so it won;'t tip.
