When we first brought CJ home, Peanut could only sniff under the door at him. However, when I came out of the bathroom and went to pick her up, she hissed up a storm and growled at me. She has never done this before, so I know it was because I smelled like Crackers.

I do believe it's normal behavior, but I don't know what to suggest you do about it other than leaving him alone when he acts like that. Try the reverse psychology thing like we're trying on Peanut. Can't guarantee results, but it's worth a try!

I'm taking it Pouncer is Alpha cat?
