No he is eating and drinking as usual, using his litter tray and nothing abnormal in his behaviour, it's really come out of the blue. He dosen't have much good luck. He was dumped in my garden about 18 months ago, in that really cold spell. He was covered in fleas had bad worms and blistered/sore pads. He was just getting over that when he was attaced by a dog who got into our garden, and had to spend a night in the vets he was so poorly. I don't know who dumped him, but he didn't know how to play as a cat could jump on the funiture, it's almost as if he was kept in a cage, and he is such a beautiful cat, inside and out.
