Maybe we should consider one. We would have to keep Ed outside while it runs, though. I'm sure he would be unable to resist chasing it and "playing" with it. He's gotten
very adept at catching the neighborhood rabbits - he would probably see this as no more than the indoor version.
The good folks at Petco have suggested that we offer him up as some sort of a product development specialist. We have returned innumerable "indestructible" pet toys in the two short years Ed has been "testing" them. He merely sees it as a challenge. I think our all-time record was a return less than 45 minutes after the time stamp on the receipt. "What on earth did this??" "Ed." "What on earth is 'Ed'"?? "He's out in the car. Wanna meet him?"
So, yeah, an Ed vs. Roomba cage match probably wouldn't last very long...
