Dad, says mum, is 'a dustbin on legs'. He hates seeing leftover food on his children's plates, so gobbles it all up - 'even the bits that are squishy and chewed'.

Then one day on a 'snack-finding snoop', he scoffs what looks like some leftover fish soup. In fact, it is the pep-up powder prescribed for the family cat, causing dad to sprout claws, whiskers and a tail - with alarming and hilarious results.
