Regurgitation Advice?

[Alexandra V]

Also he didn't have a particularly great shed last time around about 6 weeks ago, so this time I've been trying to keep his humidity higher would this have contributed?

Did you leave any stuck skin on him? Even if it isn't in a vital area or just a patch, he might just be bugged by that. Otherwise I don't think humidity would cause him any problems with regurg. Could it have maybe been something to do with the feeder? Did you thaw it out a different way than normal, or thaw it out for longer than normal, get it from a different source, etc?
