let see with mom's numberous cats and I kept snakes for 20 years I not had any issues outside one red tail tried to eat a cat one day cause I lefet th door open as I was wiring up heat tape and let te boa roam the room at the time. I heard a loud thump and abunch of cat hissing as the boa tried to constrict the cat. which I prevented for becomging a meal ( in my book dumb me since mom has way too many )
