Just from a lot of reading here on the forum, the waiting period, I'd say it greatly depends on the snake.

For temp, 90-93 warm side, 80-82 cool side, ambient (air temp) around 80 deg. should work wonderfully. Also, have at least one good hide.

Mine has been a "picky" eater her whole 6 years...at least that's what the previous owners have told me. However, not a whole lot was done to try and make sure her environment was in those ranges.

It took some finagling to get it all right. I have a 20 gallon tank. I ended up putting 1" foam on the back and sides for both insulation and privacy. Before that, I could keep the spot temps ok, but the ambient air temp would drop to 77 at night. Now it stays a constant 81 deg. 24-7.

After getting the conditions right, she ate for the first time at my house. That was 2 weeks after her previous feeding -- the shortest period between feedings she ever had, I'm told.

She just cleared the smoky eyes yesterday, so I hope she's done shedding by the end of the week. I can't wait to see if she'll keep eating well. Hope so. After shed, I'll be taking and posting pics.

Good luck with yours.
