It's very cute, and I'm sure somebuns do love it, but a lot of the buns in that 2nd You Tube clip were on leads with their owners behind them so it looked like they were jumping because they had to. I mean, if I walked behind any of the buns I had, they'd go in the direction I was going, because they thought they were being chased, even if I was slow and quiet. Lots of those buns were stopping and trying to explore.
Call me cynical, or old fashioned, but I love watching bunnies just be. Nothing nicer than watching them play and dig and binky and explore.
I agree, most ( not all) of the rabbits were only jumping because the owned was pushing their bums :roll:
