Otherwise, I would put maybe 1 tablespoon of food in his dish, giving him the impression that food was scarce so he would eat it. Later I'd give him more.I did everything else I could think of, like adding juice from a can of tuna or salmon to his food and mixing in some cooked chicken, especially when he was old and even pickier.
Basically, I gave him anything he liked and wanted to eat,wherever he wanted it, even finger-feeding him in his bed. He also seemed to enjoy being fed in unusual places. With his kidney failure and hyperthyroidism, any food he would eat was fine with me.
Poor eaters are very frustrating and I know the anxiety of wanting them to eat and fearing they'll starve. Your girlie is too adorable. I hope she'll get an appetite soon.
