At my cats yearly wellness exam this weekend my vet suggested giving my cat a fish based food because the fatty acids will help with the dandruff he gets in the winter. The dandruff does not bother him, but last winter his fur got greasy and unhealthy looking despite a wet grain-free diet, daily brushing, and a humidifier. This year in an attempt to save money he is only getting grain-free wet food in the evening and Merrick Purrfect Bistro dry in the morning (and yes, the money I'm saving feeding dry food half the day adds up to significant savings so all wet food is no longer an option). I gave him salmon oil on his wet food last winter and he liked it for a few weeks but eventually got sick of it and started either refusing food or eating around it. As a solution my vet suggested a fish based dry food instead of the chicken based food to help with the problem, but I've read so many bad things about feeding fish based foods consistently (my vet also suggested a dry only diet because wet food is "too rich" but I ignored that). Are there any other foods or supplements that can help keep a cats skin healthy .?
