Unfortunately no, that cage is not big enough. It's like two pet store cages stacked on top of eAchother, and we don't recommend pet store cages of any kind unless under special circumstances. Pigs need more floor space to run than anything, so extra levels have no importance whatsoever. I highly recommend looking into building A C&C. I guarantee it will be much cheaper than that cage, and much bigger. Plus you can customize it however you like. Building your own cage is actually a lot of fun. If you need help finding materials, just let us know where you are and we can help find stores nearby.
Also, please don't buy your pigs from the pet store. Look into adopting. There are so many pigs in shelters, and I'm almost certain you will be able to find a bonded pair easily. If you need help finding rescues nearby, we can help you there also.
edit: dang it @fay, you beat me to it! Lol
