Hi my cousins friend has a lone male guinea pig I think he is about 1 year old. I havent seen him apparently his hutch is 3ft by 2ft He eats guinea pig mix no hay or veg she wants to get rid of him my cousin told her to wait until she spoke to me I said I can take him in I have a 48inch dog crate the bar spacing is about 2 inches will this be ok for him as his other hugh is falling apart Also eventually can and how do I introduce another I don't have guinea pigs but I do have rabbits so I have a little idea
