My guinea pig is almost a year and is a very picky eater. So much to the fact he won't touch greens, and barely finishes carrots. We feed him Timothy Hay in the meantime. I was bored and poked my head into his cage and when I was massaging his back I noticed I could feel his shoulder blades. I freaked! He gets fed two large bowls of pellets a day...he drinks a lot of water...a lot! and his poops arent' hard because he won't eat ruffage! WHat can I try to get this pig to eat to plump him up???...I've tried Parsley, lettuce, spinach leaves, I even bought him gourmet salad bags, he won't eat broccoli, apples he munches on but they just rot in his cage, doesn't touch any other fruit...what do I do????
