I agree, Neodesha cages are very well-made & secure. When I did programs with native rattlesnakes, I had smaller* Neodesha cages in which they traveled securely,
though I customized the vents with another wire mesh screen, leaving a large gap between so that IF someone got near my cages AND put their hand on the screen
vent, and IF a rattlesnake decided to tag them, their fangs couldn't go thru both screens plus the 1" gap. The pegs that keep the sliding glass locked can be replaced
with padlocks for travel & shows also. My only challenge using Neodesha was that when you get substrate or feces in the track, the door will be hard to slide, as the
glass is already heavy. The way the glass slides also limits where you can put these & still open them, but all cages have pros & cons. (*I had large Neodeshas too)
