My sister discovered that her cat’s fur was highly collectable. I was delighted when the postman arrived at the door with a sample for me. It came in a 6″ x 4″ crinkly clear plastic bag decorated with black lettering cut out from sticky-back plastic. It didn’t look worth £12.50 and I wondered if it contained fleas, but others were apparently clamouring for it to the extent that the poor cat was now almost bald. We left the pack unopened on the sideboard in the hall, unsure whether or not to open it due to my cat allergy.
