fancy-X-crosses they don't get near as big as the SW's my supplier grows.
Years ago when i kept Lg. boids rats was all i did, now days i just do mice, i've found that a 4-6 ft colubrid does fine on 2-3 jumbo mice per week.
Rat pups and small rats are great for colubrids and they don't smell as bad, but they require more sq. area and eat much more than mice.
