First and foremost, my ferrets like to scratch and dig. I give them a new pile of grocery bags, paper and plastic, and they always go inside for a look. I sometimes give them a bunch of paper towels, for them to de-roll and scratch. I have a large box full of uncooked rice and other grains for them to dig in. they love to be buried in this stuff.! Finally, they like jingle-balls. The types that are tied to a string are fun, or the types that go loose. They try to grab them and move them around,,, sometimes playing soccer. Mark h.
