Mine only like the green plastic tunnels, and cardboard boxes with holes cut in them. Or potential food toys like willow balls, their treat ball, and what I call their weeble (egg shaped which dispenses treats but always pops upright just like a weeble). I havent been able to get them interested in chews, loofah/sisal/wood or rattle balls etc. The only other thing they like are small flower pots to throw around.
However, curtains, the sofa, carboard folders they love to chew - basically anything they shouldnt be!
