My cat is about 3/4 years old. She is fairly small, as far as cats go, healthy and athletic, and weird recently. I've been coming home and I've seen her pretty much anywhere, looking around at a speed that grants her a 180 degree sight-angle, and generally being weird. Weirdest, she doesn't complain much when I pet her during this, but she's usually pretty darn antisocial. Any clues on what might be causing this? I don't know how long it's been going on, I noticed it yesterday.
