What kind of interaction do you think the prairie dogs have with the rattlesnakes?

Rattlesnakes would eat a prairie dog if they could catch it. However, if a rattlesnake approached a prairie dog colony, the prairie dog's "sentinels" would alert the rest of them, and they would hide in their holes. A rattlesnake could fit into the holes, but I don't think that snakes usually actively seek prey (they act more like a trap, waiting for prey to come to them).
