My Gracie did that and as has been suggested above she did better with several smaller meals a day. I had to keep a variety on hand as what was eaten one day often wasn't the next. Wet foods mixed in with kibble, smelly foods ... sardines, Jack Mackerel, tuna, wet cat food either alone or mixed with a bit of kibble. Vanilla Insure, cottage cheese, crock pot rice and chicken thighs cooked until gloopy. She loved store bought rotisserie chicken ... breast only! and would often eat that with smashed potato or rice. In other words I fed her whatever she would eat, some days it was just Milkbone cookies and some vanilla Insure.
Carl, now 13.5 is starting to skip meals or eat just one meal a lot later in the day, so far adding Parmesan cheese or Tripett green tripe does the trick.
