It Is A Fact,

that cats like boxes,

I have no idea why, 

but that like of boxes gave Chris Pool an idea, He made a maze for his cats Cole and Marmalade, the idea is so simple you can set up all 50 boxes, or 25, or 10 boxes, in some cut out a bottom door so the cats do not have to jump, and hey presto! a room sized cat toy! 

so the next time I see a pile of flat stack boxes I must remember to buy some of them!
