Unfortunately those cubes aren't available on ebay any more

I was going to get Oscar one. He's very playful but he doesn't do drugs - not valerian, not honeysuckle, not catnip. He also won't chase a laser dot! "You expect me to chase a red dot ??

!!" he says.
His very favourite toy is a ribbon. He also likes the plastic ribbon sized straps that come off a zooplus box or other package. I attached a ball of halls soothers wrappers (he likes the smell of those) on to the end with a rubber band.
