2 pigs in my cage

I bought a cage from a pet store for my one pig but I'm 16 years old and when I stay at a friends house I am sometimes gone for a day or to but when I come he seems lonley I would like to buy another pig and introduce them but my cage is 2 feet long and one foot wide would that be big enough for two? When I'm home my pig is out of the cage ALOT I pay a lot of a attention to him but I feel sorry for him when I'm gone. Please let me know what you piggy lovers think.
Thanks
Shell(me) and Scampers (my little man)

First off I would build a C&C cage for your pigger then get him a friend. As long as its the same gender or plan on getting him neutered. If you dont know what a C&C cage is itz a cubes and coroplast cage and to get more info on it you can go to this website.

check it out it will be worth your while and if you already have checked it out you should consider building that kind of cage.

I would like to build a C&C cage but my mom wont let me. So should I just not get my pig a friend??

Your mom wont let you build a cage that is defintly cheaper then a pet store cage? Thatz weird but anywayz I would try and find a bigger pet store cage or something because it would be better if your pigger had a friend.
