sliding doors would be a NO NO for venomous reptiles for me .
i use glass tall tanks for venomous .besides that sliding doors & flip opens give the animal too much time to get a chacne to get away or tagg ya . even though just aboutall my cages are sliding lgass and flip opens .thats the only drawl back with me .venomous stuff, maybee elapids and such wouldnt be such a good idea in a sliding glass or flip open but crotalus n vipers r slower calm animals u might not have a problem changing n feeding stuff. but garters are very high strung and active .could be a pain when your cleaning a water bowl or such when there paired up in there . that gets fun , especialy with a trio trying to get out =)
