It was a classic case of clinical depression.
The patient would not go out for fear of being bullied, moped around the house and sought comfort in eating. Eventually there was nothing for it. Twiglet the cat had to be put on Prozac.
The 12-year-old grey tabby, whose weight had ballooned to 15lb, became one of the first pets in Britain to be given anti-depressant drugs, on the advice of a vet who said she had 'anger management issues'. And the results have been dramatic. Five months later, Twiglet has lost almost 7lb and is roaming around the back garden without fear.
