Are your cats attached to their food dish. We have had Kody for a little over a year. Since we had him he's always used the same small blue dish for his canned food. Well the other day awful person that I am broke that little blue dish. I tried every extra cat dish and small human dish I had to put his canned food in but he wouldn't touch it!!!
My daughter had to go out and look all over till she found a dish that was exactly like his (only difference was this one had a fish on it). Only then would he eat the canned food!! Thank goodness she found one or I don't know what I would have done. You better believe we are going to to get him a spare!!!
