Okay, my guinea pig, Peaches, is unusually large. Not only is he almost a foot around, but he is very long. When I first got him, he wasn't eating much, because he was scared all the time. I think I started to over feed him. I feel like a terrible owner. Now, his natural instict is to store up fat for the winter. Well, he treats his pellets like candy, so I cut him down on those. Now, he only gets them occasionally. I always keep his hay filled, because that is essential. Though, he eats all that, too. He is lazy, but the sweetest, most cute thing in the WHOLE WORLD!!!!!! I love him so much and I want to do what's best for him. HELP!
