If you are really worried about RI from the litter you can get a covering for the box, just move it to a different room when you scoop it.

Just please make sure there is no way your snake can get out and the kitty can't get close enough to tamper with the lid. We dont want them to cross paths. Not everyone can have a snake room but just be extra observant since they share a space when you aren't home.

I know my Ember would find my future snakes fascinating *paw paw at glass* God help me when I pick up rat breeding "MOMMY! PLAYTOY!"

BTW there is harm to humans. Women who are pregnant cannot scoop litter, airborne bacteria in the feces can cause some minor birth defects. Not sure if its still true, but my dad had litter duty for 9 months.
