Linds: Yep, Ernie is fixed. That was crucial to me before I even considered taking on a prairie dog. I think the biting stemmed from the sudden change of environment, but with any luck he will be easily handleable by spring time. (fingers are crossed) You're right though, pd bites hurt and I've seen the results many times. Multiple employees at my workplace have been bitten and lets just say, there was a demonstration of how blood can fly. It wasn't pretty.
Jason: did you get both at the same time? I would love to add a friend for mine, but I'm worried about the territorality issue considering he will have been on his own for close to a year when I will be ready to possibly take on another.
