LOL... funny story.Delilah misses ALL the time, and usually looks embarrassed by it. I think she was actually relieved when we offered F/T last week, because she finally didn't have to worry about the strike - she was like, "Yes! They did all the work for me!"
She took that thawed mouse faster than she's ever taken live, which made me very happy.
As for feeding in/out of their enclosure, I've always fed mine inside of theirs without a problem. I even hand-feed Delilah sometimes (with tongs), and she's never been aggressive about it... guess it just depends on the individual snake.
