Mine has an odor as well and he has not had cancer. His teeth; however, were knocked out when he got hit by a truck so maybe it is that (we havent been to the dentist yet- insurance as well) but it seems as if the smell is coming out of his skin even. He stays in the bathroom for a very long time and when I bring it up he is VERY, VERY defensive. He gets so mad so its hard to bring it up to get it fixed because he gets so mad. I dont know what to do but honestly, its a turn off and I dont even let him kiss or hug me anymore :(. Guess ill make a doctors appointment and he can just get over it.
