My cats love these little fabric cat cubes that i get for them at the local pet store. When they come out of the box they ARE a cube shaped toy and the first thing my cats do is rearrange the shape. They jump on it, slide thru it and crush it until they get it just the way they want it.
When they are thru with it, it looks just like this
It's all misshapen, hairy and slashed...Just perfect!
