"Are you serious? You actually think a kitten would be useful?" he said, staring. "You do realise that in three years of fighting the Yeerks, we needed a cat morph a total of once. And that was because the place we needed to infiltrate had a cat, so we couldn't just acquire any cat - we needed the right one. And that turned out to not work so well anyway, because we had to keep making sure the real cat wasn't around every time. There are other morphs that are better, more effective, and don't have the same risks."
