I would give my right arm to understand cat psychology.

We have a new cat, well, a cat that showed up last summer looking like death warmed over, who has made a miraculous recovery - anyhoo - the other cats and this cat do this growling-staring-walking really slow and close to the ground- thing when this cat is near. I’m sure he is giving off some sort of signals to them, but I cannot figure out what they are. There have been no fights with injuries, just all this growling and posturing - I would love to know what it all means.
