Bastet had to go on new food at the beginning of the year and she refused to eat it. The vet suggested sardine juice (only from sardines in spring water mind you) it contains very little fat and she wolfed it down. Now she loves her new food and I don't have to put sardine juice on it anymore. BTW if given in small doses (once or twice a week) sardineds are fantastic for kitty's skins and coats and also if they have poop problems.
