Since these guys live such short lives me and my wife were talking about getting two more this summer so that they're offset from our current 4 which will all be about a year old at the time. We were thinking about getting a couple of girls and spaying them so they can all live together. Does anyone know what the rough cost is to have a girl spayed? I know it varies, just looking for a ball park. Is it dangerous? What age should it be done? If we're use to boys would this be a good idea? Or should we just stick to boys?
