I feed about a heeping tablespoon daily, some days none. I just got my last batch from Hare Today as my local supplier went out of business. It was $110 for 50# including shipping(I went in w/ my friend to get a larger bulk order, cheaper that way) I was getting it for $1.60# locally
Before that I ordered from A Place for Paws - Columbiana, Ohio - Tripe - The Other White Meat and may go back there again next order.
