....when you throw your back out getting pussy..... to stick his paw through the hole in the box! My cat loves playing in a box (similiar to pic) where you wiggle a glove or small toy through the holes, and try to pull it away before he snatches it. Last night I was crouching down and yanked the glove back real fast....and threw my back out for a few minutes. WTF? I used to do PT every morning, run a couple/three miles a day, do combatives (ground fighting basically) with other 190 pound guys, etc. Now I can't even play with my cat without warming up?
