Simple. boxes that things come in. Plastic bands that hold milk caps on. Paper clips. Jewelry that happens to be lying on top of your bureau. Rubber bands you forgot to throw away. NO, these are not exactly acceptable cat toys, but these are the things MY 4 decide to constantly steal and play with day after day, regardless of the $2,000 worth of REAL cat toys in their "toy corner" that they ignore from day to day. Another thing they love is (besides "whatever falls on the floor") is the caps from my insulin syringes. There must be at least 100 of those batted underneath my stove, refrigerator, couch, bureaus, etc.
