Millie has been wormed regularly, and no chance she's pregnant! She was spayed at 5 months and is not an outdoor cat anyway. We have a new kitten here as a playmate for Millie and this past week that we've had her, they've done nothing but play play play, so hopefully that will help too. We have had 3 other cats, and no problems with weight whatsoever, so this is a new experience for me, especially this at 7 months old.
