Can you maybe feed the other cats while you hold Carmello or put Carmello in another room until the other cats are done eating? And then feed Carmello alone after you put the other cats in another room or outside? It will take a bit of time to teach them the routine, but it will work you just have to be patience. Or...when you feed all the cats, put a seperate dish down Near you for Carmello and if the other cats come to eat out of his dish...shoo them away. And if Carmello tries to eat out of their dish....shoo him away with a stern voice and tell him no...and put him in front of his dish. Its tough love with the kitties, but they will do good and will learn the routine as long as you stick with it.
