Strange feeding habbit

YUP myth! As to substrate ingestion I have laid down a bit of plastic to feed on but generally especially with my spider he drags his food all over the enclosure and gets it covered in substrate. He has eaten aspen,cyprus,and coco coir. All with out troubles, I have watched dissection of a wild burm and it had sticks in its belly, lots of sticks. I don't really bother with the substrate guard anymore the coco coir I am using is fine particles and easily passable.

I started off feeding in a dedicated feeding area. Then she decided she didn't want to eat there anymore, so now I don't.

Feed your snake where ever it will eat. That's pretty much the only thing you really have to worry about.

Try using a smaller enclosed feeding container. Also I feed all of my larger females in their tubs and non of them have aggressive behavior with when opening the cage. I suppose it just depends on the snake as well. I had a normal male that used to get aggressive upon the cage opening but he no longer does that.

As stated already, feeding in their enclosure will not create aggression. I've fed my baby in her tank since day 1, and a solid year later, that's what shes used to, along with being the sweetest thing. Only time she's ever gone into strike mode on me, is if I go to grab her on feeding day before feeding her. Even then, she still hasn't struck at me. ;)
