Okay, we all know the housing space guidelines. My suggestion to the OP is to review them
Guinea Pig Cages, Your Cavy At Home. In the mean time, until you can find the space for a large enough cage, perhaps we all can work together to offer suggestions to make the most of the space the OP does have access to.
I know when I was new to guinea pigs, I thought the store cage I had was just fine - because I wasn't aware that there was a better option but I understand the frustration of lack of space. I have seen people in the same situation get suggestions for rearranging furniture.
To the OP: You did come to this forum and started a thread asking if the cage you have is better for rabbits or guinea pigs. When people started to answer, the question that you posted, you insisted that you knew better. What you may want to think about is - if you do know better "My pigs are happy, thank you very much", then why post the question in the first place? If you posted the question, why scoff at the answers? My other suggestion is to stand back and just listen to what people have to say. They are trying to answer your question. Take what you will from the answers given, discard others, it's up to you.
