Marbles....

"Cats sleep anywhere, any table, any chair.
Top of piano, window-ledge, in the middle, on the edge.
Open drawer, empty shoe, anybody's lap will do.
Fitted in a cardboard box, in the cupboard with your frocks.
Anywhere! They don't care! Cats sleep anywhere."

By Eleanor Farjeon

A favourite childhood poem of mine and one of my cats 'Marbles' who definately likes to sleep anywhere!!!
