Ok. Here's why... When I first got Penny, she had been fed in her viv. She was almost 5ft and had an insane feeding response. Dangerous even. I mean if she smelled thawing rodent, you couldn't get near her. I decided to try using a bin for her to see if it changed her behavior any. The first few times eating in the bin, she would still strike at me through the bin, but after about 6 feedings, she mellowed out. Now, she still eats every time, but there is none of the feeding aggression that she used to have. Maybe because of the bin, maybe not, but I am happy with her attitude so I am not changing the routine.
