I've just got guinea pigs for the first time and I had no idea what I was doing. I got information online that said that I should look for the biggest cage I could find, stating that most commonly bought cages are too small. I found this one for perusing the internet. It's huge. I love the divider that keeps the mess of the feeding and watering on one side and the play area on the other. Loved the free shipping and it got here really fast. The only downside is that the canvas is a little tricky to put on the wiring and it's a little flimsy. Okay, so there's two downsides. Just give yourself enough time to put the cage together (twenty minutes or so) and don't expect to be able to carry your pigs in the cage.
