I own three royals, 1 also being a pastel. Imo he doesn't look that skinny.. but the weight says it all. I would honestly stick to 5 days. If he happens to refuse the next feed in 5 days I would leave it a week then feed him again but I think he should take in the next five days. While you can kill a snake via power feeding yes, and I totally disagree with power feeding, feeding a young snake that may be a little underweight every 5 days won't kill him, I promise you.
When my 07 Pastel came to me last year he was already on adult mice.
But i got him straight on to large rat weiners (all F/T) as I believe rats are healthyier, and hes growing just right and has turned into a handsome little boy.
Unfortantely they do fade alot as they grow - but are stunning animals nonetheless. Good luck with the little fella
Umm, i would say about 2 months - 10 weeks. Then move to the next size up. Post pictures in about 2 months and we estimate when you should move up better =]
I dunno man....If it is, I would totally be fine with that. I think the adult is gorgeous. And yea, I dig the Adult pastel over an adult normal ANYDAY.
