You know, i used to like drop down 1 piece doors too....but then i got a retic. You have no idea how many times a sliding door has saved me from Caesar's ravenous baby appetite lol. He has literally sucked onto a glass door with mouth fully open like that fachugger at the beginning of aliens 2 in the glass tube that tried to suck onto Burkes face. Plus it helps out a ton also in the fact i can just open the door opposite where the bitey end is for my snakes. When they smell food, they tend to bite first and taste second which if I'm not quick enough has ended with a bruised hand from my sunglow lol. I got lucky and dodged Caesar a week or so ago by jumping back but i tripped backwards over a chair lol.
