I put her on a kitty "diet." Switched both of them to twice-daily feedings instead of free-feeding and put her on a reduced calorie food. First it was Pet Gold light, then Natural Balance light which she grew to hate and now she's on Royal Canin light which she seems to love. I don't buy the grocery store brands for my kitties. I also try to spend some time with her each day playing and encouraging her to run and jump. It didn't happen overnight! It's taken her a little over 7 months to lose half a pound. She's still "fluffy" (she IS a long-haired cat, after all ). I suspect my little Mitzi will always be a bit round, but that's what makes her SO cute and cuddly.
