I know this is probably one of the most heated/hated topics when it comes to snakes so lets not get this out of hand too far.

I was told one time by someone ( dont know if they were on these boards or some other board) that rats are more healthlier than mice for snakes.

Does any one have any solid proof of this being true? Other than the fact rats are bigger so the less you food you have to feed your snakes each month.
