Go to one of the big stores like Home Depot or Lowes; they have vinyl privacy fence, and I think it comes in 4' high sections (or something close). It's vinyl, so it cleans well. It's solid, so no escapees. You can add gates. And I'm pretty sure you can figure out a way to bolt them to the floor.
Best of all? If you decide you don't need the partition anymore, you can use it to fence off an area outside for them as it's completely weather proof.
Hope this helps, or at least gives you a starting point. |
