My brother says im feeding her too much. He says im supposed to feed her once every 4 days? I feed her daily. I know shes hungry when shes walking around wandering. If i dont feed her daily, she starts eating the soil there is which has her poo in it..... o__o And im worried she'll get sick. And my brother says we spend too much money on spring mix and santa barbra mix. SO yes please help. Thank you.
