I've noticed within the last couple of months that if Lexi is on the floor wanting food, or just roaming, and comes to one of us, that she will duck or cringe really low when we try to pet her. She does this each time as if someone is about to hit her. We found her as a stray and this makes me think that someone hit her in the past. We have never hit or abused her for any reason. Anyone else have any ideas?
