Samantha loves when I shake my computer chair too. Her being front declawed, I try not to shake too hard for fear of flying kitty, but she just loves it and bites down on the fabric, and attacks it with her paws. I also sing to her, and we have multiple conversations a day. Samantha really doesn't play much with toys...once in a while we can get Da Bird going, and she loves her Catfish but she really just carries him around meowing loudly. She, more or less, watches me jump around like an idiot trying to entertain her, and I think she gets her enjoyment outta that, haha!He also likes me to jiggle him on the back of the computer chair. He digs into it with his claws and I sit in the chair and jerk it back and forth. He hangs on and bites at it and growls like he's on the back of a Waterbuffalo.
