They really love each other - of course, they are sisters: Garrida, the tortoiseshell cat, and Zarca, "the one with the blue eyes". Hard to believe, considering what they look like. Typical story: Mum is a Portuguese mongrel, Dad unknown.
They are now 3.5 years old and catch the mice. Zarca even catches rats. Garrida is more likely to catch mice, but never under stress, and never doing without her after-lunch sleep!
