Yes, they aren't in a C&C cage, but they also don't live together. Unfortunately, Abbie is great with people, but is very aggressive with other guinea pigs(to the point of drawing blood). I think that it comes from being in a pet store situation with many other pigs in too small an environment. Before I am admonished for buying her, remember that I have only started really doing guinea pig research online about a year ago and was entirely ignorant of the existence of guinea pig shelters until then! I joined this forum to learn more about C&C cages and designs, esp since I live in a rather small apartment with my fiance. They are in the largest size Marchorio cages I could find and are able to see each other, which they seem to like.
I try to give them as much floor time as possible, using most of the living room for their puttering. I can usually put them out together, since when Abbie starts food guarding or getting aggressive, I can move Maggie away from her until she calms down.
As for more about my girls, Maggie is 4 and I first had her as a solo pig during my last year of college. She is very bonded to me and loves nothing more than timothy hay to stretch out in and munch. Abbie is 2 and is the quirkiest pig I've ever had. For example, she can only eat things from the tip down. If she picks up a piece of hay in the middle, she painstakingly nibbles it around until she gets to an end before she munches it down.
ETA the cages are 36" long and 19" wide.
