Snake weight

49g is pretty small but not unheard of. I would double check those mice though because if they really are even 20g, that's quite large for a 49g snake and he is going to need extra time to digest. A small fuzzy mouse is more appropriate.

I wouldn't rush him. He will eventually catch up if fed properly.

I've recently been successful with my first clutch and hope this might be some useful information for you.

My smallest snakelet was 48g out of the egg, and 57g the largest. Once they had their first shed, none were fed anything larger than 15g (frozen) rat fluffs, thawed then warmed in water for a heat signature.

Now at just over 2 months old, and the least fed on seven meals, all the snakelets left here (others now with a local seller) are over 100g.
In my current open pack of fluffs, my smallest is 13g and the largest 18g (again, frozen). Once these are gone, I'm moving up to the mid-20g feeds.

All my snakelets are now smashing the feeds, toileting well and shedding cleanly.

Hopefully, my process may help you decide on your best actions moving forward, but as Nikkubus says, 20+g feed seems quite big for a little guy.
Might it be worth trying a few weeks on sub-20's to see if he takes more regularly and enthusiastically for you?
