Of the many games the cats play one of their favourites is making tunnels in the runners and hiding toy mice in them or in Zazzles case pieces of string,bottle tops,foliage,Ellen's hair bands and lots more of his treasures.
If one cat is in a tunnel and the other comes in it is a safe bet they will leap on to the tunnel and a game of chase starts. It is good fun for them but dangerous for the unwary walker. Zazzles is resting after stowing some of his his treasures
