JazzCat is correct, that's a good way to train cats. You also have a Jack Russel? :) That's lovely. They should get along fine as long as they are raised together, you shouldn't have any problems. :)

"Life is life - whether in a cat, or dog or man. There is no difference there between a cat or a man. The idea of difference is a human conception for man's own advantage." ~Sri Aurobindo
