When Desdemona went to the vet last week, she'd gained about 3/4 lb since her last visit in March. The vet would like to see her drop that amount, so she's going on the all-canned-food diet that's been successful for us before (she'd currently been getting about 1/8 cup of Evo dry for breakfast, canned for dinner). The vet also suggested adding some canned pumpkin to her meals to add a bit of "bulk" so she feels fuller. How much, would you think? I'm guessing not more than a teaspoon or so.
