One of my cats eats elastic, rubber hoses, plastic carrier bags and her favourite, sellotape! She used to eat paper and cardboard, but seems to have gone off these. That was a nightmare as when she was a kitten, she used to climb up the backs of drawers and get into drawers from the back and eat photos and important documents. As both her and her brother can open doors, nothing was sacred wherever you put it! Her brother sometimes eats fluff and licks the carpet. As he is incapable of coughing up his own hairballs, he also has to have a laxative. They also used shred the curtains a lot (still do occasionally), and Smokey is so strong he used to pull the curtain rails straight out through the plaster. They have also destroyed a computor, a telephone, a mobile phone charger, a leather suite and 3 dining chairs. They are little monsters, but would not change them for the world, except perhaps the plastic and sellotape eating, as that does worry me. Believe me, you are not alone.....
