Okay, a few days Vor I was in the backyard and I see a black cat in the neighbors yard(and I do not know these neighbors). Now, I walk over to the fence and do that sound we make to get Katzen to come to us. But the cat doesn't come to me it just stays there. So I walk around the baum for a few Minuten then the cat goes towards the fence, curious bout the sounds across the street. So I walk towards the fence and the cat comes to me. And i pet it as best I could through the fence and then I think the cat growled at me(and yes Katzen can growl) so I pull my fingers away and then the cat goes back...
