I'm nearly certain that LJs weight loss is down to his teeth, but if I'm wrong after reading a lot of info, it's apparantly common for cats with diabetes to develop CRF. Obviously, I'm very concerned abou this and want any information any of you may have on treatment of CRF in diabetic cats. If I do this now it means if I get the worst case scenario, I'll know what treatments are available and won't go into meltdown quite so spectacularly.
