Another inexpensive toy is what we called a pizza hat
--it's those little plastic three-legged
table-like structures often put in pizza boxes
to prevent the box
and smudging the cheese
These have the perfect cat toy bounce dynamics, plenty of surfaces for the cat to grab, and the legs can be bitten by the cat and they can carry it around the house like a dead mouse. Our hyperactive cat will actually play fetch with the thing like some sort of dog.
