Gideon, a stray nine-year-old cat, was adopted by a kind family. His brother Mau, who was also adopted, is four years younger. Although they are not related, they have the same brown-gray fur. Together, they share the warmth, shelter and love of their owners. Gideon and Mau encounter a tired and hungry calico lady cat. Mau tries talking to the calico cat but is met with an unfriendly response. Gideon advises his brother to let her be. They then meet another cat with ginger-coloured fur, which looks equally hostile. This cat tells them that they are uncared for and seeing cats who are well cared for makes them angry. Read on to find out how the cats fight, understand each other and go on to become thick friends.
