My parents cat, Minnie, is the mother of my two boys and all of those cats LOVE ice cream or milk. The best part it how they act around it though. Say your sitting at the couch, they will sit next to you or on the arm rest and as you lift the spoon to your mouth, the cat twists its head upside down. Then as you lower the spoon it turn its right side up. I have to watch my boys though or they wont hesitate to dip their paw into the bowl themselves.
Dairy products must be a huge draw. My old cat found a red plastic cup with a little milk left in it in the middle of the night. He decided to stick his entire head in to drink it. He actually got his head stuck! My sister found him walking around our living room blindly running into things. She pulled it off, and its lucky she got there because I think he might have suffucated.
