I know that many people always think that Hello Kitty is not a cat. But to me compare to somebody, she is DEFINITELY a cat because I can tell her design and I always know what she is. Yes, she acts, talks, and behaves like a human, but at the end, she's a cat, an anthropomorphic cat.
Personally, I generally hate how some people always think most fictional anthropomorphic animal characters are not what they really are (like for example, they always think that Mickey is not mouse, Goofy is not a dog, Snoopy is not a dog) because it's kindda stupid because I'm smart, and I know what species of those animal characters are despite their human behaviors and doesn't even matter to some people. No offense.
