Goshalas

Hello friends! I'm a Mexican girl flying to India and my main goal is to visit and volunteer in a Goshalas. I study philosophy and I'm currently writing about animals and religion, im so concerned about the cows that are seen as a part of a community. I'm planing to visit Mumbai and Goa. Does anyone know any goshala I could visit and stay a couple of days, also, what else do you think I should do to get to know more about indian culture relating to animals
