"I guess it would depend on the size of the rabbit"
Yep. Swamp rabbits are quite a bit bigger than your average run of the mill cottontails. Not as long or tall as a jackrabbit, and not quite as heavy, but still heavier than a standard cottontail. Yes, it is a
different species than your average bunny. Note the weight, they go heavier than 6 lbs -- that's one hefty bunny in the wild.
