It's good to see that there are petshop managers who know their snakes. Personally, I would say that as long as they aren't fed each time their cage door is opened, they will not associate it with feeding time.
Besides, you can give yourself hernia trying to move a large snake from enclosure to enclosure.
:I am a manager of a Pet Store in Salt Lake City, Utah. I have had many constrictors including Burms, Red Tails, Bloods, and Balls. I am thuroughly convinced to feed in side the cage. The owner of the shop disagrees with me about this practice. I would like everyone's opinion, please. I would like some reasons to take back to him to convince him to side with me on this issue. Please help!! Thanks!!
