Siamese Agression

Question
We recently adopted a beautiful female Choc Point from the shelter. She is 10 months old and is beautiful. I have two male Siamese which have been with us for 10 years. One is a Snowshoe the other is an Oriental. The problem is the aggression of the new cat. No sooner did I introduce the newbie to the older animals, she immediately jumped on the Snowshoe and attempted to bit his neck. She tried the same to the Oriental. The two males are twice her size and weight. The newbie knows no fear.We try to re-introduce, for the last 2 weeks on a 1/2 hour basis but no change in aggression. The vet gave us some anxiety drops for the newbie but they don't seem to help. The older males are 'ready to do battle' each time and don't back down as well. HELP please. Thanks Joe.

Answer
Joe,

Thanks very much for your fantastic feedback, I appreciate the time that you took to rate my answer and I'm so glad that I was able to help you to decide which step you needed to take next. Generally when it comes to Rescue Remedy I usually use the human version which you can find in just about any health food store. The human Rescue Remedy has always worked very well for cats that have needed it so I've stuck with it, after all as the old saying goes "If it ain't broke..."
