We liff with a pazz kitty and all he wants to do is playplayplay. He keeps us all up all day. Short of making our hooman take him back to the shelter,

That's the problem with younger kitties...they're usually in full on crackhead mode and they have so much energy it comes out in a giant display of SPAZZZZ. There's not a lot you can do about it, other than wait until he grows out of the crackhead phase.

Well...you CAN corner him and sit on him every time he annoys you. Little kitties don't seem to enjoy being squashed by the 'Tocks of Doom. It won't stop him from spazzing out, but it'll make you feel better.
