LOL.... mine are almost 5mths, they are too small to actually jump on things, but I swear they have springs in their back legs. They just jump straight up and down for the pure joy of jumping. I figure it's good for them as they are probably strengthening their legs? But, yes they jump...all the time..jumping beans is a very apt description.
