These animals went through an artificial selection and over generations and millennia had their behavior and morphology changed by humans. This process of domestication by man gave rise to a special ability, the understanding of human pointing gestures, clearly noticed while we feed our pets. Our goal in this study was to assess the comprehension of pointing gestures by cats and also verify the influence that social interactions exerts on the development of this ability. We found that experimental subjects from both groups, solitary animals and social animals, were able to follow human indication in order to find hidden food. However, social interaction had no effect on cats performances. The ability tested here probably evolved during the process of domestication of this species, and social interaction seems to exert little or no influence upon its expression / AOs gatos (Felis catus) foram domesticados h? cerca de 9.500 anos devido ? agricultura, onde eram utilizados no combate ?s pragas que assolavam os alimentos colhidos. Esses animais passaram por uma sele??o artificial e ao longo das gera??es e mil?nios tiveram seus comportamentos e morfologia modificadas pelos humanos. O processo de domestica??o pelo homem fez surgir uma habilidade em especial, a compreens?o de sinais gestuais humanos, que ? bem observada nos momentos em que alimentamos nossos animais. Nosso objetivo neste estudo foi testar a resposta ? sinaliza??o gestual (comportamento de apontar) em gatos, emitida por humanos e tamb?m verificar a influ?ncia do conv?vio social sobre o desenvolvimento desta habilidade. Observamos que os sujeitos experimentais de ambos os grupos, animais solit?rios e de conv?vio em grupo, foram capazes de seguir os sinais de indica??o humana para localizar o alimento escondido. Por?m, a forma de conv?vio social n?o influenciou no desempenho dos gatos. A habilidade aqui testada, possivelmente evoluiu durante o processo de domestica??o dessa esp?cie, e a intera??o social parece exercer pouca ou nenhuma influ?ncia sobre a sua express?o
