Yep they have to figure out their own Pecking Order My calico cat MindySue is 12yrs-30lb of Queenliness She barely tolerates the rest of my furry family a 3yr old Kitten -3yr old Manchester-a12 1/2 yr old Min-Pin - but when she speaks {growl-hiss] they listen--- It really won't take long before they figure out that all of them are loved and they are all staying :-D
