Your cat is not eating any wet food??

I had a problem with my cat as he did not touch the wet food at all after the day before when he really liked eating it. So I was not sure what was happening. Then I bought about 1/2 pound of ground beef, and freeze it in small portions in the ice cube tray. Every day I put one ice cube of ground beef in boiling water (very quickly) and mix it within the regular wet food. Now my cat eats it without a problem at all.
