I got 1 guinea a few weeks ago from a relative, she pretty much just stayed in her hidey hole all the time, acting depressed, so I took my kids down to get Cuddles a friend, and wound up getting 2. They are currently in a 2x3 c&c cage with a 2x2 c&c attached. I pulled all the dumb moves like introducing before health time and separating as soon as there would be a possible argument, but I think I get the rules now. I will be introducing them really soon, but what size of un-used c&c do I do this intro in? The 2 that I bought from the store were out on my couch last night wheeking and purring and playing around on my lap, then I held Cuddles, she just nuzzled closer to my face if I stopped petting her, but no purring. It was a complete and instant change when Cuddles saw the two new piggies next to her, she started popcorning and playing around. I really want to have them all in a 2x5 all together, without getting nervous that they will hurt eachother. Our black piggie came to us with a 3rd of her ear missing already.
