Technical kudos to Dave Evans for developing a GPS tracker device for his cat's collar:
Mr Evans, 41, said the weatherproof tracker, weighing just 15g, will cost £50 and can be used for cats and dogs. He said: 'My cat was getting fat even though I was feeding him less and I needed to know what was going on.Allowing owners to track where their cats go and from which houses they get additional food? I can't imagine the feline population standing for that kind of interference. I foresee Mr. Evans coming to a sticky end, mysteriously breaking his neck while walking down the stairs. Mr. Evans - move into a bungalow post-haste, and may I advise you to trade in your cat for one of the larger varieties of canine?
Now I know he travels a couple of miles each day, exactly where he goes every night and who's feeding him.'
