Well I'm glad you are going to feed her more. It may sound odd but... Do you get a weekly allowance? I used mine to buy Molly, Astra, and Prince some Wellness when we used to be feeding Purina. I read the label and heard that corn wasn't good so I switched foods. You can ask your mom to take you to your local petstore to buy some better food. As suggested, you need to feed Roxy more. Molly is on a diet and she gets 3 cups of food a day. And to say this is coming from someone younger than Brianna.
