Q. I lost a cat to cancer 2 weeks ago. Could the canned food I gave her at night have caused the cancer.
DR. CHRISTIE LONG, D.V.M., C.V.A.
A. I'm so sorry you lost your cat. At this point I know of know definitive research that suggest a link between commercial cat food and cancer. Unfortunately we are still struggling to understand exactly why animals and people get cancer, so it might be a long time before we're able to answer the question of why cancer happens. But I really don't think there's a link between the food you fed and the development of disease. Again, I'm so sorry.
