Fiona McCade (Perspective, 26 December)wrote about the waste of money spent buying Christmas presents for pets.
Our tabby, Sir Ernest Shackleton Brown, got a packet of catnip. He rolled in it, chased his tail, ran out of the house at 100 miles an hour and headbutted the cat next door. He is now swearing he will never touch catnip again.
