When Tink was little, I had to sit on the floor next to her food dish and hand feed her each little piece. Otherwise, she wouldn't eat. I think that lasted about 4 months and then she would bring a mouthful of food to me for me to feed her.

So I stopped that routine! She has always been a picky eater.
I started her on Nutro, but after the dog food scare (she was also sick with other problems) I switched her to Wellness and she loves it. I don't have to worry about her eating.
Try hand feeding and see if it helps. Good luck.
