thank you everyone. He's been for a six month MOT. Vet said his heart sounds dreadful and that he really shouldn't be with us! His lump although big hasn't changed much in the last six months. He has lost quite a bit of weight though which isn't good, which shows the lymphoma is having an effect on him [although at moment he's not a thin cat] Vet was overjoyed though to see him looking so well and delighted to be proved wrong at his estimate of two weeks!!!
