This is a really unfair question! Answering it is actually a lot harder than I would think. My cats are very different in personality, but it actually evens them out in my eyes. My older cat, Nell, is everything I ever wanted in a cat. She's very low-maintenance, doesn't want much attention, comes to demand petting sessions herself, even plays by herself sometimes! She's the kind of cat that acts as a master of the house, she likes to find a high spot and look down on us disapprovingly. My younger cat, Heathcliff, cannot be more opposite. He only wants attention, every minute is petting time, and he won't even come himself, he sits/lies around and meows until I pick him up. I would normally choose Nell as my favorite, but when Heathcliff puts his paws around my neck like he's hugging me, and starts rubbing my cheek in my face, I just melt inside.
