Prairie dogs?

Does anyone on here have a prairie dog as a pet?? Or have had one in the past? I came across an ad in CL (I know, I know!) and I'm curious about these little guys. Their owner seems to really care about them since he wrote a HUUUUGE post about them. I've been looking around on the internet for information but the PD community is severely slacking on their forums!

Any input would be greatly appreciated! Thanks
