Hello! I need help with putting a diet on my bigger guinea pig. She's overweight and I'm not sure what to give her to make her smaller. She has always been overweight, since I got her. Her friend/sister though is not overweight and perfectly healthy. I give her hey and just a little bit of pellets in the morning. Alas I cannot give them fresh vegetables either, as my mother says it is too expensive to keep buying them. But Cutie (that's her name) has no problem moving around, as she's doing just that right now. I always see her eating, but not her sister, Lily. Lily is fine, though, and she eats till' she's full. But is Cutie overeating due to stress? Or can she not tell when to stop eating? Thank you for reading.
<-- That's Cutie. My first post explains Lily, if you are interested in learning about her.
