This time last year I was agonising because my Mum and Dad had left their cat with me, and it was perfectly obvious to me that he was dying of Diabetes, but they wouldn't admit it. I got him diagnosed and fixed up while they were out the country, but I was worried that they wouldn't be able to cope with the twice-daily insulin regime. I was proved wrong - they have faithfuly injected him for a whole year, and I am now looking after him again, and he is completely like a new cat. I can see him out the window right now, menacing a squirrel on the fence (the squirrel, oh rodent-fans, is unconcerned). He's literally twice the weight, scampering about the place like a maniac, and he grooms himself now. So, thanks for the online advice which helped me decide it was OK to overrule their wishes and get him sorted out.
