I do that with cats a lot, yeah, especially cats. I think "wow, there is this LIVING creature here, it's alive and moving and thinking and just so small and delicate... and it's a cat! Dogs have been very domesticated, but cats have really only ever been bred to look certain ways. They retain most of their instincts... this is a small piece of the wild right here! Some are lazy and silly, but still.. A small cat right in front of me!" And then I am fascinated by watching them walk, seeing how they shift their weight, watching their shoulders as they stalk something on the top of the couch... Gets intense. Sometimes I just end up staring at my cat in awe. I'm strange.
