If you go for an AP cage, make sure to get the shelf option. All my snakes love their shelves. I'm using 3 T10s and 1 Constrictor NW cage. But will be changing up my 2 boas and retic to T25s later.
I use flexwatt for all of them except the Pro-Line cage which is a RHP which i'd rather have flexwatt on that too.
And using a Herpstat 2 Redline on one of the cages and Herpstat 2 normal on the other as well as 2 more Herpstats on some other stuff.
And you can see Rosey, my 6.5' girl wanting to get in on the photo too lol.
