I know a lot of cat breeds as well as dogs. It's just harder to tell if a cat's fur is a morph of its breed or a whole nother one. Like, black corgis are still corgis. A gray cat could be virtually anything.
This annoys me SO MUCH! I mean, you have to start over the problem and everything! This happens to me all the freaking time!^^ I don't even do the problem again. I just pick the closest answer to mine.
