They are sisters, they both came from the SPCA at the same time.
At first Spot dominated Alice Ann, beat her up terribly.
Alice Ann had enough of that, and now the attacking is about equal although
Alice Ann remains about the size of a coke can. Spot now grooms her little sister and looks out for her.
They are good sisters!
They're adorable and I want to meet them when they're of a spinnable age.
