Okay so I just recently switched my new Super Pastel male over to F/T. I was a bit down when I first tried, but from my experience, a few things helped me. Patience, just keep trying! Don't get down and keep trying. Second, I tried right after he dropped a sock-of-snake-skin and was extremely hungry, and right after, he snatched it right up. I might try after the shed, because my guy really was hungry, and while he wouldn't even look at it before, he even tried to resist the F/T this past time, but in the end, he was much to hungry to resist it, and finally struck. Just my 2cents. Hope it helps
