For great piggie info , I would suggest the
guinea lynx website.
http://www.guinealynx.info/guinealynx It's more directed to medical problems, though.
But here is some of my own info:
Guniea pigs should be fed a high quailty diet, which consits of
timothy hay, fruits and veggies, and a good quailty pellet(avaible daily). Guinea pigs do better in same sex pairs, as they love company, and you dont have to deal with pregnancy problems, or bringing more piggies into the world, taking up homes for the animals who have none

. They need ample room, so they can run around and play. I follow the cage set-ups at
http://www.cavycages.com . They have a directions to make great cages
