-on the revised feeding schedule. BTW- don't bother feeding him when he clouds up (goes into a shed cycle). Even if he's willing to eat then, it can cause problems with a stuck shed, because both shedding and digestion require good hydration (they use up water in the snake's body). Many snakes (even those not underweight) may have trouble with "multi-tasking" both functions.
I'm glad if he didn't actually have stuck eye-caps, & yes, it's possible & likely that dehydration caused lines (fine wrinkles) in his eyes that appeared to be left-over eye-caps from a previous shed.
For that reason (& because snakes in the wild don't have "room service" & don't eat when in shed anyway) that I'd advise not feeding him when he's in shed, no matter how eager you are for him to gain weight. A snake's body doesn't regain good body weight OR hydration quickly, so just be patient. Eating while in shed will likely result in a stuck shed for this snake in the foreseeable future.
You're lucky to have a good exotic vet nearby. And from your intelligent questions, I'd say he's already in good hands.![]()
