Animal Plastics Belly Heat

[Skiploder]

I got my Animal Plastics T12 today. They forgot to bring the flexwatt with them so they are sending it tomorrow. However they mentioned something about sliding the flexwatt into place when it gets here. However, I cannot for the life of me figure out where I'm supposed to slide this flexwatt belly heat. Does it just go on the bottom of the cage on the outside? I can see where the heat cable can be slid into place but no where for me to slide in flexwatt. Can anybody help me out?

Do they make a different bottom section depending on the heating type? One routered for the cable and one slotted for the flexwatt?

If so, it sounds like you may have gotten the wrong bottom section................
