Apparently my pet, Crookshanks the cat, can sense Animages somehow. I'll have to be careful; either I learn Animagism in places where Crookshanks can't get at me in my altered form, or get rid of Crookshanks. I'd truly dislike doing that, partly because it's nice having one being in my life that I can trust. Of course, it could have been that Crookshanks just could sense that Scabbers was a Death Eater. I'll have to try exposing him to real, unrepentant Death Eaters, when we capture some, and see how he responds.
