I had a Calico that would only eat dry catfood. Thats all she wanted, even turned her nose up at canned food and Tuna.
Our “longest serving” cat, Flower, was also a calico. She lived to be 19 and was truly a harmless little fuzzball, she was afraid of her own shadow. She would eat tuna, a little, but no other human food, except lamb chops, she was crazy about them.
Those brought out a completely different side of her personality. Every time we had them she’d jump up on the table and steal a bone then sit on the floor gnawing at the remnants of meat like a wild animal.
And our last cat would only eat yogurt and ham. She loved ham, but nothing else, not even other pork foods.
