I agree completely with the others, although I highly recommend getting a parasite check, 10 days is not nearly enough to be concerned. I would also recommend cutting down how much you feed the snake, as I honestly believe hognoses can be overfed. Chances are it has met its caloric demands and is taking a break from constantly digesting food. The vast majority of snakes in the wild, across all species, have empty stomachs when caught. Hognoses do not need to eat every four days!

... nature has ceased to be what it always had been - what people needed protection from. Now nature - tamed, endangered, mortal - needs to be protected from people. When we are afraid, we shoot. But when we are nostalgic, we take pictures.
