Welcome Emily to the Plush Cats Club! I know half a cup of kibble a day doesn't seem like much, but they WILL get used to it. Mine did (two feedings a day instead of free-feeding) and are now galloping throughout the apartment. I'm not too sure how much the plush little Ms. Mitzi has lost - she's still round, but she does seem to have more energy. She gets her exercise running away from Mishi!
