So when I rescued my boars,(Two pigs) the owners gave me a 2 by 3 C and C cage. I'm confused whether or not that a safe size since people on this forum have been saying that commercial cages such as the midwestern and XL Living world cage are good sizes for two piggies, yet they are smaller than a 2 by 3. I have been wanting to have my dad make an extension for their cage but I'm still waiting. Should I just keep a 2 by 3?
