41 quarts is a bit over kill for Hognose snakes 32 quarts will be big enough, and for Milksnakes they work fine.

I currently keep Milksnakes and Bullsnakes in the 41 quarts economy line and plan on keeping my Hognose snakes once full grown in a 32 quarts.

Keep in mind that temp requirement of Milk and Hognoses differs.
