Gracie does this stalking thing to Cubby. As soon as Cubby turns around Gracie charges him. When we catch her doing the whole body language we tell her to leave him alone and sit. She then will charge him. If we say nothing she will still charge him. Today she had him in a corner sniffing him. She also pokes his belly with her nose. This cat is afraid of pretty much anything and so far Gracie isn't really helping him get over his fears of 'big dumb dog'. It is really driving us nuts as well as Cubby. Cubby is to the point now, that he will stay a good 5 feet away from her so he has a head start to run under something. I know Gracie doesn't want to hurt him, she just wants to play, lick and sniff. Is there any way I can stop this?
