I've had Aussie dogs for nearly 20 years to assist with the animals, all were "rescue" dogs. I had to send one away out of 6 as not being able to fit in and work with other animals or people. The last one is 16 now and she still "guards." She too, get the "bat ears" when she gets excited or curious. My best to you and Kenzie and when she figures out that the cat belongs to her, at her house, there should be harmony.
