toby is a major jumper..... he has been bounding off couches and the bed since we got him at 12 weeks old..... i tried stairs, but that didnt work, i think he figured it was "too much effort to walk down stairs and he would rather just take a flying leap" .... oh well,.... he hasnt hurt himself yet, (he is larger though....... he is 9 lbs)...... so hes not a tenny that can get hurt easily.... i worry just the same though
