My cats like raw best, but one will only eat kidney or liver. I try not to give too much liver due to Vitamin A abundance in it. Neither like their food minced but will only eat it diced. The boy Timmy will pick out kidney from any mix and leave the rest. To solve this, and to make sure he gets calcium I make DIY kibble with bone meal and calcium powder. They will also not eat anything with additives, so one a week I give a squeezy Lic a Lix treat with taurine, omega 3 and vitamin E mixed in.
If anyone could advise on how I might get him to eat in a normal fashion I would be very grateful!
