So im wondering how small of a space can non-baby ball pythons fit through. Both of mine are just under a year one like 500 grams the other like 300. I built my own tank display and ended up with about a 1/2 gap between the top of the enclosure and the frame of my shelf system. Can ball pythons fit through a half inch?? I know in 6 months or so ill have no worries but for the size they are now can they squeeze through a half inch??
