Given how utterly unreasonable some people can be over the keeping of snakes, I think things went really well for you.
One valid concern I would imagine landlords might have is what they would do if one of your snakes (or anyone's) escaped and disappeared into the walls of the building. That risk would warrant a higher deposit, in my opinion. But of course, as a tenant, I would never bring that up myself!![]()
Regarding the placement of "locks"...my hubby is the same way with my little rack. It HAD to have some kind of mechanism that would prevent the snakes from pushing their tubs out (which is actually not possible to do..it'd be like trying to pick yourself up by your boot straps...but yeah...whatever). I'm not sure what kind of rack system you have, but if you can drill a small hole through the middle of each shelf, you can insert a pin/dowel/fat nail/doodad/whatever in each hole. Depending on how it's set up (and what kind of pin you end up using), they can either block the upper lip of the tub from sliding out...or brace against the bottom of the tub to keep it from sliding. I'm sure you can find something inexpensive at the hardware store that would serve as a suitable pin.
