Hi, I've actually worked my way up from the original CB 2000 in black to the CB 3000 clear and up to the CB 6000 with both cages. However my new Princess like the look of the CB 2000 cage as it allows her to "harass" her toy. I can make the cage work with the CB 3000 rings. But I'd really like to be able to use the CB 6000 rings as they are the most comfortable. Is there anyone out there making the original style cage that would fit the 3000 rings? Or maybe a whole original style cage with 3000 rings set up? I'm sure that my princess can't be the only one who likes the looks of the old style cage. R@@ver
