Hi Michelle, When my was anemic and wouldn't eat I tried raw she really didnt like it most of my cats do not some do. My homepathic vet told me that I should not feed raw to a fiv/felv cat. That it's better to blanch it and feed semi raw. Now I know some vets say yes and some say no. Depending on the vet.
You may try and blanch 1st and see if that helps and work up to less and less cooked, you know try fully cooked then semi and then raw and mix it together also I did that when I wanted to get a cat to eat raw if they don't raw then little by little less and less cooked. Carla
