My 6 month old cats are jumping on top of my china cabinet. Is there anything I can do to deter them?

I have bought them with jingle bells inside and a cat pirate ship play thing...I have given them cardboard boxes to play in...They tear up my curtains, tablecloth and silk flowers...I have removed the throw rugs they were peeing on! ...I am scared to think of putting up a Christmas tree.. I need advice with real solutions to curb their rambunctious ways! And yes, my husband and I play with them when we are home. I thought having two would solve the boredom problem...
