My cat was just diagnosed as FLUTD and currently has a catheter in place(still in the early days). I was advised to put him on the Hills c/d food which I have no problem with. The recommended feeding is 75g per day (just over half a cup) but for my cat who has been free feeding this is nowhere near enough for him and begs for more food! How much of this can i feed him and can i feed him raw pet mince on top of the hills food to satisfy his needs?
