Decipher Cat Behavior
About a month ago we got a new cat. She was isolated in a room until recently. Now we have let her out, and our existing male cat seems to meow loudly and make a low grumbling noise when he is looking for her. I'm having a hard time deciphering if he is threatening her or not. I have a video but cannot post it to this sub it seems.
Any ideas how to decipher this behavior?
