It takes quite a while for an underweight snake to actually gain weight so that it's noticeable to you...and weighing a snake constantly is stressful, so
don't over-do that. What is the temp. on the cool end of his cage? He must be able to get away from the 92* warm end.
He does need to fill out & gain weight but be patient: the pet store you got him from is "typical"...they under-feed snakes so they don't out-grow the
cage they're in, because "small" (aka 'baby') critters are more appealing to their average buyer, & because they're cheap-skates when it comes to food.
But please, don't feed another item so soon (4 days?) after the first one, as that can cause a regurgitation (a real set-back); no matter how small the
prey item, wait a week to feed another (or even longer, for larger prey). You were lucky. He looks curious in that photo, that's a good sign. But I
wouldn't handle him much, if at all, for a few more weeks (& that includes weighing him) while he's settling in. New homes are very stressful, snakes
are shy.
And by the way, he's very pretty! Welcome to the forum, and to the love of snakes. In case no one warned you, they can be very "addicting".![]()
