Piggies make great pets! I have to agree that they do take a lot of work and thought to feed, but they're well worth it. ^_^

Making a cage is the best option, I made one for my piggies, and they love it.

But... if you can't make a cage, or can't find the materials, this petstore cage is excelent (and cheap too!) I have it for my rabbit. You can find it at Petco:

yes, it may be a little smaller than what is recommended, but it's not too cramped for 2 piggies. Make sure they get some supervised time out of the cage too.

Good luck!!!
