Does your kitty like a variety? Mine is stuck on Purina Dry only, won't eat anything else.
I had him on the pouch stuff from Iams he liked that. But when I fed him Fancy Feast after the recall he promptly threw it back up.
He does like the raw chicken livers, raw eggs and tuna I have been giving him for snacks.
Grind up some kidney, liver, heart, etc., and then slowly start adding to kitty's dry food and as kitty starts to eat it then slowly decrease kibble and increase the beef heart and the organ meats... you can lightly steam the meat, the smell will sometimes tempt them more if steamed.
