Having a larger cage isn't a matter of opinion. It's a matter of life or death, and at the very least comfort, for your pig. Pigs who live comfortable tend to be healthier and happier and live longer as a result. The people on these forums probably WOULD speak to each other that way if we all met in person because the common denominator here is providing safe, happy, healthy homes for our cavies. They're just giving advice for healthier piggies and OP is shirking it off as though it's not important for your babies to be well cared for.
