Hi all: It's Sylvia and George. George has been on 1U, bid, of Lantus since Nov. 23rd and is doing great. Overnight, I put two bowls of Tiki dry and Orijen dry (with very small amounts in the bowls). George does not even like hard food. I believe my other cat, Bailey, eats it. Is it important or necessary that George have ANY DRY FOOD? Thanks.
