I kept my rattlesnakes in large glass tanks (aquariums, designed to hold the weight of water, are very hard to break, unlike "glass terrariums") with tops I built myself out of wood frames with wire mesh ("hardware cloth"), & on the 4 corners of the tops I installed eye bolts, & on the wood cabinets the tanks sat on was a chain with a snap bolt (like a dog leash) that effectively "locked" the top onto the cabinets underneath. Even Fish & Game was fine with my security, cleanliness & good care. (I had a home check for a "Detrimental species" permit for some non-local rattlesnakes that I ended up with.) I much prefer to work with hots from overhead, not from the front.
Never had a problem, but my methods were my methods.My rattlesnakes were throughout my house too (including my bedroom) & not locked in a snake room, but without kids around I never felt it was any kind of safety issue. Especially since I didn't work them with hooks, where they might slip off & get loose. I made "shift cages" for them- it was much less stress for all concerned, &
I could even safely bathe them with the way my design worked. When I took in some rattlesnakes previously kept by others, they usually stunk from having been kept in filthy cages, & they actually appeared to enjoy a bath, but they were also clearly surprised by it.![]()
