I've never actually seen it in a store so I wouldn't know. It seems terribly small though, less than 2 feet long and little over a foot and a half wide. It's high, because it's meant for chinchillas and rats who like to climb whereas guinea pigs really need more space spread out rather than going up.

I still think that you can make a good catproof C&C cage and it would probably be a lot cheaper then that cage.
