Ive been reading up on alota sites describing how to breed the guinea pigs.....although i still have a couple questiosn because most of the information i read was about "Pet Guinea Pigs" not feeders lol

First and to me most important question would be if the guinea pigs were locked in one room in Dog crates with door closed could my 7 foot burm smell them 2-3 rooms away??? I think so but im not 100% Sure

Also what would be the best food to feed a guinea pig to plump him up so the snake gets the most nutrition possible???

Also any other pointers possible.......pros and cons welcome to !!!!
